gnuwin32: Remove old versions of bison/flex from the distribution
The win_flex/win_bison tools are already in the repository and working with all projects, so the GnuWin32 versions can be removed and the winflexbison versions can take their place. Task-number: QTBUG-46852 Change-Id: I41bc541adab834ff83912d7a4f076a87fc174601 Reviewed-by: Lars Knoll <lars.knoll@theqtcompany.com> Reviewed-by: Kai Koehne <kai.koehne@theqtcompany.com>

-This directory contains data needed by Bison.
-
-* Skeletons
-Bison skeletons: the general shapes of the different parser kinds,
-that are specialized for specific grammars by the bison program.
-
-Currently, the supported skeletons are:
-
-- yacc.c
- It used to be named bison.simple: it corresponds to C Yacc
- compatible LALR(1) parsers.
-
-- lalr1.cc
- Produces a C++ parser class.
-
-- lalr1.java
- Produces a Java parser class.
-
-- glr.c
- A Generalized LR C parser based on Bison's LALR(1) tables.
-
-- glr.cc
- A Generalized LR C++ parser. Actually a C++ wrapper around glr.c.
-
-These skeletons are the only ones supported by the Bison team.
-Because the interface between skeletons and the bison program is not
-finished, *we are not bound to it*. In particular, Bison is not
-mature enough for us to consider that ``foreign skeletons'' are
-supported.
-
-* m4sugar
-This directory contains M4sugar, sort of an extended library for M4,
-which is used by Bison to instantiate the skeletons.
-
-* xslt
-This directory contains XSLT programs that transform Bison's XML output
-into various formats.
-
-- bison.xsl
- A library of routines used by the other XSLT programs.
-
-- xml2dot.xsl
- Conversion into GraphViz's dot format.
-
-- xml2text.xsl
- Conversion into text.
-
-- xml2xhtml.xsl
- Conversion into XHTML.

-# but is not used by Bison (as recorded by macros in the namespace
-# BISON-NAMESPACE).
-#
-# USER-LIST must expand to a list specifying all grammar occurrences of all
-# names of type WHAT. Each item in the list must be a triplet specifying one
-# occurrence: name, start boundary, and end boundary. Empty string names are
-# fine. An empty list is fine.
-#
-# For example, to define b4_foo_user_names to be used for USER-LIST with three
-# name occurrences and with correct quoting:
-#
-# m4_define([b4_foo_user_names],
-# [[[[[[bar]], [[parser.y:1.7]], [[parser.y:1.16]]]],
-# [[[[bar]], [[parser.y:5.7]], [[parser.y:5.16]]]],
-# [[[[baz]], [[parser.y:8.7]], [[parser.y:8.16]]]]]])
-#
-# The macro BISON-NAMESPACE(bar) must be defined iff the name bar of type WHAT
-# is used by Bison (in the front-end or in the skeleton). Empty string names
-# are fine, but it would be ugly for Bison to actually use one.

-# This skeleton produces a C++ class that encapsulates a C glr parser.
-# This is in order to reduce the maintenance burden. The glr.c
-# skeleton is clean and pure enough so that there are no real
-# problems. The C++ interface is the same as that of lalr1.cc. In
-# fact, glr.c can replace yacc.c without the user noticing any
-# difference, and similarly for glr.cc replacing lalr1.cc.
-#
-# The passing of parse-params
-#
-# The additional arguments are stored as members of the parser
-# object, yyparser. The C routines need to carry yyparser
-# throughout the C parser; that easy: just let yyparser become an
-# additional parse-param. But because the C++ skeleton needs to
-# know the "real" original parse-param, we save them
-# (b4_parse_param_orig). Note that b4_parse_param is overquoted
-# (and c.m4 strips one level of quotes). This is a PITA, and
-# explains why there are so many levels of quotes.
-#
-# The locations
-#
-# We use location.cc just like lalr1.cc, but because glr.c stores
-# the locations in a (C++) union, the position and location classes
-# must not have a constructor. Therefore, contrary to lalr1.cc, we
-# must not define "b4_location_constructors". As a consequence the
-# user must initialize the first positions (in particular the
-# filename member).

-# In M4 1.4.x, every byte of $@ is rescanned. This means that an
-# algorithm on n arguments that recurses with one less argument each
-# iteration will scan n * (n + 1) / 2 arguments, for O(n^2) time. In
-# M4 1.6, this was fixed so that $@ is only scanned once, then
-# back-references are made to information stored about the scan.
-# Thus, n iterations need only scan n arguments, for O(n) time.
-# Additionally, in M4 1.4.x, recursive algorithms did not clean up
-# memory very well, requiring O(n^2) memory rather than O(n) for n
-# iterations.
-#
-# This file is designed to overcome the quadratic nature of $@
-# recursion by writing a variant of m4_foreach that uses m4_for rather
-# than $@ recursion to operate on the list. This involves more macro
-# expansions, but avoids the need to rescan a quadratic number of
-# arguments, making these replacements very attractive for M4 1.4.x.
-# On the other hand, in any version of M4, expanding additional macros
-# costs additional time; therefore, in M4 1.6, where $@ recursion uses
-# fewer macros, these replacements actually pessimize performance.
-# Additionally, the use of $10 to mean the tenth argument violates
-# POSIX; although all versions of m4 1.4.x support this meaning, a
-# future m4 version may switch to take it as the first argument
-# concatenated with a literal 0, so the implementations in this file
-# are not future-proof. Thus, this file is conditionally included as
-# part of m4_init(), only when it is detected that M4 probably has
-# quadratic behavior (ie. it lacks the macro __m4_version__).
-#
-# Please keep this file in sync with m4sugar.m4.

-# m4_foreach(VARIABLE, LIST, EXPRESSION)
-# --------------------------------------
-# Expand EXPRESSION assigning each value of the LIST to VARIABLE.
-# LIST should have the form `item_1, item_2, ..., item_n', i.e. the
-# whole list must *quoted*. Quote members too if you don't want them
-# to be expanded.
-#
-# This version minimizes the number of times that $@ is evaluated by
-# using m4_for to generate a boilerplate into VARIABLE then passing $@
-# to that temporary macro. Thus, the recursion is done in m4_for
-# without reparsing any user input, and is not quadratic. For an idea
-# of how this works, note that m4_foreach(i,[1,2],[i]) defines i to be
-# m4_define([$1],[$3])$2[]m4_define([$1],[$4])$2[]m4_popdef([i])

-# Implementing `foreach' loops in m4 is much more tricky than it may

-# | # foreach(VAR, (LIST), STMT)

-# | [m4_pushdef([$1])_foreach([$1], [$2], [$3])m4_popdef([$1])])

-# | [m4_define([$1], _arg1$2)$3[]_foreach([$1], (m4_shift$2), [$3])])])
-#
-# But then if you run
-#
-# | m4_define(a, 1)
-# | m4_define(b, 2)
-# | m4_define(c, 3)
-# | foreach([f], [([a], [(b], [c)])], [echo f
-# | ])
-#
-# it gives
-#
-# => echo 1
-# => echo (2,3)
-#
-# which is not what is expected.
-#
-# Of course the problem is that many quotes are missing. So you add
-# plenty of quotes at random places, until you reach the expected
-# result. Alternatively, if you are a quoting wizard, you directly
-# reach the following implementation (but if you really did, then
-# apply to the maintenance of m4sugar!).
-#
-# | # foreach(VAR, (LIST), STMT)
-# | m4_define([foreach], [m4_pushdef([$1])_foreach($@)m4_popdef([$1])])

-#
-# which this time answers
-#
-# => echo a
-# => echo (b
-# => echo c)
-#
-# Bingo!
-#
-# Well, not quite.
-#
-# With a better look, you realize that the parens are more a pain than
-# a help: since anyway you need to quote properly the list, you end up
-# with always using an outermost pair of parens and an outermost pair
-# of quotes. Rejecting the parens both eases the implementation, and
-# simplifies the use:

-# | # foreach(VAR, (LIST), STMT)

-#
-#
-# Now, just replace the `$2' with `m4_quote($2)' in the outer `m4_if'
-# to improve robustness, and you come up with a nice implementation
-# that doesn't require extra parentheses in the user's LIST.
-#
-# But wait - now the algorithm is quadratic, because every recursion of
-# the algorithm keeps the entire LIST and merely adds another m4_shift to
-# the quoted text. If the user has a lot of elements in LIST, you can
-# bring the system to its knees with the memory m4 then requires, or trip
-# the m4 --nesting-limit recursion factor. The only way to avoid
-# quadratic growth is ensure m4_shift is expanded prior to the recursion.
-# Hence the design below.
-#
-# The M4 manual now includes a chapter devoted to this issue, with
-# the lessons learned from m4sugar. And still, this design is only

-## --------------------------------------------- ##
-## 10. Defining macros with bells and whistles. ##
-## --------------------------------------------- ##
-
-# `m4_defun' is basically `m4_define' but it equips the macro with the
-# needed machinery for `m4_require'. A macro must be m4_defun'd if
-# either it is m4_require'd, or it m4_require's.
-#
-# Two things deserve attention and are detailed below:
-# 1. Implementation of m4_require
-# 2. Keeping track of the expansion stack
-#
-# 1. Implementation of m4_require
-# ===============================
-#
-# Of course m4_defun AC_PROVIDE's the macro, so that a macro which has
-# been expanded is not expanded again when m4_require'd, but the
-# difficult part is the proper expansion of macros when they are
-# m4_require'd.
-#
-# The implementation is based on two ideas, (i) using diversions to
-# prepare the expansion of the macro and its dependencies (by Franc,ois
-# Pinard), and (ii) expand the most recently m4_require'd macros _after_
-# the previous macros (by Axel Thimm).
-#
-#
-# The first idea: why use diversions?
-# -----------------------------------
-#
-# When a macro requires another, the other macro is expanded in new
-# diversion, GROW. When the outer macro is fully expanded, we first
-# undivert the most nested diversions (GROW - 1...), and finally
-# undivert GROW. To understand why we need several diversions,
-# consider the following example:
-#
-# | m4_defun([TEST1], [Test...REQUIRE([TEST2])1])
-# | m4_defun([TEST2], [Test...REQUIRE([TEST3])2])
-# | m4_defun([TEST3], [Test...3])
-#
-# Because m4_require is not required to be first in the outer macros, we
-# must keep the expansions of the various levels of m4_require separated.
-# Right before executing the epilogue of TEST1, we have:
-#
-# GROW - 2: Test...3
-# GROW - 1: Test...2
-# GROW: Test...1
-# BODY:
-#
-# Finally the epilogue of TEST1 undiverts GROW - 2, GROW - 1, and
-# GROW into the regular flow, BODY.
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: Test...3; Test...2; Test...1
-#
-# (The semicolons are here for clarification, but of course are not
-# emitted.) This is what Autoconf 2.0 (I think) to 2.13 (I'm sure)
-# implement.
-#
-#
-# The second idea: first required first out
-# -----------------------------------------
-#
-# The natural implementation of the idea above is buggy and produces
-# very surprising results in some situations. Let's consider the
-# following example to explain the bug:
-#
-# | m4_defun([TEST1], [REQUIRE([TEST2a])REQUIRE([TEST2b])])
-# | m4_defun([TEST2a], [])
-# | m4_defun([TEST2b], [REQUIRE([TEST3])])
-# | m4_defun([TEST3], [REQUIRE([TEST2a])])
-# |
-# | AC_INIT
-# | TEST1
-#
-# The dependencies between the macros are:
-#
-# 3 --- 2b
-# / \ is m4_require'd by
-# / \ left -------------------- right
-# 2a ------------ 1
-#
-# If you strictly apply the rules given in the previous section you get:
-#
-# GROW - 2: TEST3
-# GROW - 1: TEST2a; TEST2b
-# GROW: TEST1
-# BODY:
-#
-# (TEST2a, although required by TEST3 is not expanded in GROW - 3
-# because is has already been expanded before in GROW - 1, so it has
-# been AC_PROVIDE'd, so it is not expanded again) so when you undivert
-# the stack of diversions, you get:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST3; TEST2a; TEST2b; TEST1
-#
-# i.e., TEST2a is expanded after TEST3 although the latter required the
-# former.
-#
-# Starting from 2.50, we use an implementation provided by Axel Thimm.
-# The idea is simple: the order in which macros are emitted must be the
-# same as the one in which macros are expanded. (The bug above can
-# indeed be described as: a macro has been AC_PROVIDE'd before its
-# dependent, but it is emitted after: the lack of correlation between
-# emission and expansion order is guilty).
-#
-# How to do that? You keep the stack of diversions to elaborate the
-# macros, but each time a macro is fully expanded, emit it immediately.
-#
-# In the example above, when TEST2a is expanded, but it's epilogue is
-# not run yet, you have:
-#
-# GROW - 2:
-# GROW - 1: TEST2a
-# GROW: Elaboration of TEST1
-# BODY:
-#
-# The epilogue of TEST2a emits it immediately:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# TEST2b then requires TEST3, so right before the epilogue of TEST3, you
-# have:
-#
-# GROW - 2: TEST3
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a
-#
-# The epilogue of TEST3 emits it:
-#
-# GROW - 2:
-# GROW - 1: Elaboration of TEST2b
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3
-#
-# TEST2b is now completely expanded, and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW: Elaboration of TEST1
-# BODY: TEST2a; TEST3; TEST2b
-#
-# and finally, TEST1 is finished and emitted:
-#
-# GROW - 2:
-# GROW - 1:
-# GROW:
-# BODY: TEST2a; TEST3; TEST2b: TEST1
-#
-# The idea is simple, but the implementation is a bit evolved. If you
-# are like me, you will want to see the actual functioning of this
-# implementation to be convinced. The next section gives the full
-# details.
-#
-#
-# The Axel Thimm implementation at work
-# -------------------------------------
-#
-# We consider the macros above, and this configure.ac:
-#
-# AC_INIT
-# TEST1
-#
-# You should keep the definitions of _m4_defun_pro, _m4_defun_epi, and
-# m4_require at hand to follow the steps.
-#
-# This implements tries not to assume that the current diversion is
-# BODY, so as soon as a macro (m4_defun'd) is expanded, we first
-# record the current diversion under the name _m4_divert_dump (denoted
-# DUMP below for short). This introduces an important difference with
-# the previous versions of Autoconf: you cannot use m4_require if you
-# are not inside an m4_defun'd macro, and especially, you cannot
-# m4_require directly from the top level.
-#
-# We have not tried to simulate the old behavior (better yet, we
-# diagnose it), because it is too dangerous: a macro m4_require'd from
-# the top level is expanded before the body of `configure', i.e., before
-# any other test was run. I let you imagine the result of requiring
-# AC_STDC_HEADERS for instance, before AC_PROG_CC was actually run....
-#
-# After AC_INIT was run, the current diversion is BODY.
-# * AC_INIT was run
-# DUMP: undefined
-# diversion stack: BODY |-
-#
-# * TEST1 is expanded
-# The prologue of TEST1 sets _m4_divert_dump, which is the diversion
-# where the current elaboration will be dumped, to the current
-# diversion. It also m4_divert_push to GROW, where the full
-# expansion of TEST1 and its dependencies will be elaborated.
-# DUMP: BODY
-# BODY: empty
-# diversions: GROW, BODY |-
-#
-# * TEST1 requires TEST2a
-# _m4_require_call m4_divert_pushes another temporary diversion,
-# GROW - 1, and expands TEST2a in there.
-# DUMP: BODY
-# BODY: empty
-# GROW - 1: TEST2a
-# diversions: GROW - 1, GROW, BODY |-
-# Than the content of the temporary diversion is moved to DUMP and the
-# temporary diversion is popped.
-# DUMP: BODY
-# BODY: TEST2a
-# diversions: GROW, BODY |-
-#
-# * TEST1 requires TEST2b
-# Again, _m4_require_call pushes GROW - 1 and heads to expand TEST2b.
-# DUMP: BODY
-# BODY: TEST2a
-# diversions: GROW - 1, GROW, BODY |-
-#
-# * TEST2b requires TEST3
-# _m4_require_call pushes GROW - 2 and expands TEST3 here.
-# (TEST3 requires TEST2a, but TEST2a has already been m4_provide'd, so
-# nothing happens.)
-# DUMP: BODY
-# BODY: TEST2a
-# GROW - 2: TEST3
-# diversions: GROW - 2, GROW - 1, GROW, BODY |-
-# Than the diversion is appended to DUMP, and popped.
-# DUMP: BODY
-# BODY: TEST2a; TEST3
-# diversions: GROW - 1, GROW, BODY |-
-#
-# * TEST1 requires TEST2b (contd.)
-# The content of TEST2b is expanded...
-# DUMP: BODY
-# BODY: TEST2a; TEST3
-# GROW - 1: TEST2b,
-# diversions: GROW - 1, GROW, BODY |-
-# ... and moved to DUMP.
-# DUMP: BODY
-# BODY: TEST2a; TEST3; TEST2b
-# diversions: GROW, BODY |-
-#
-# * TEST1 is expanded: epilogue
-# TEST1's own content is in GROW...
-# DUMP: BODY
-# BODY: TEST2a; TEST3; TEST2b
-# GROW: TEST1
-# diversions: BODY |-
-# ... and it's epilogue moves it to DUMP and then undefines DUMP.
-# DUMP: undefined
-# BODY: TEST2a; TEST3; TEST2b; TEST1
-# diversions: BODY |-
-#
-#
-# 2. Keeping track of the expansion stack
-# =======================================
-#
-# When M4 expansion goes wrong it is often extremely hard to find the
-# path amongst macros that drove to the failure. What is needed is
-# the stack of macro `calls'. One could imagine that GNU M4 would
-# maintain a stack of macro expansions, unfortunately it doesn't, so
-# we do it by hand. This is of course extremely costly, but the help
-# this stack provides is worth it. Nevertheless to limit the
-# performance penalty this is implemented only for m4_defun'd macros,
-# not for define'd macros.
-#
-# The scheme is simplistic: each time we enter an m4_defun'd macros,
-# we prepend its name in m4_expansion_stack, and when we exit the
-# macro, we remove it (thanks to pushdef/popdef).
-#
-# In addition, we want to detect circular m4_require dependencies.
-# Each time we expand a macro FOO we define _m4_expanding(FOO); and
-# m4_require(BAR) simply checks whether _m4_expanding(BAR) is defined.

-## 15. Set handling. ##
-## ------------------ ##
-
-# Autoconf likes to create arbitrarily large sets; for example, as of
-# this writing, the configure.ac for coreutils tracks a set of more
-# than 400 AC_SUBST. How do we track all of these set members,
-# without introducing duplicates? We could use m4_append_uniq, with
-# the set NAME residing in the contents of the macro NAME.
-# Unfortunately, m4_append_uniq is quadratic for set creation, because
-# it costs O(n) to search the string for each of O(n) insertions; not
-# to mention that with m4 1.4.x, even using m4_append is slow, costing
-# O(n) rather than O(1) per insertion. Other set operations, not used
-# by Autoconf but still possible by manipulation of the definition
-# tracked in macro NAME, include O(n) deletion of one element and O(n)
-# computation of set size. Because the set is exposed to the user via
-# the definition of a single macro, we cannot cache any data about the
-# set without risking the cache being invalidated by the user
-# redefining NAME.
-#
-# Can we do better? Yes, because m4 gives us an O(1) search function
-# for free: ifdef. Additionally, even m4 1.4.x gives us an O(1)
-# insert operation for free: pushdef. But to use these, we must
-# represent the set via a group of macros; to keep the set consistent,
-# we must hide the set so that the user can only manipulate it through
-# accessor macros. The contents of the set are maintained through two
-# access points; _m4_set([name]) is a pushdef stack of values in the
-# set, useful for O(n) traversal of the set contents; while the
-# existence of _m4_set([name],value) with no particular value is
-# useful for O(1) querying of set membership. And since the user
-# cannot externally manipulate the set, we are free to add additional
-# caching macros for other performance improvements. Deletion can be
-# O(1) per element rather than O(n), by reworking the definition of
-# _m4_set([name],value) to be 0 or 1 based on current membership, and
-# adding _m4_set_cleanup(name) to defer the O(n) cleanup of
-# _m4_set([name]) until we have another reason to do an O(n)
-# traversal. The existence of _m4_set_cleanup(name) can then be used
-# elsewhere to determine if we must dereference _m4_set([name],value),
-# or assume that definition implies set membership. Finally, size can
-# be tracked in an O(1) fashion with _m4_set_size(name).
-#
-# The quoting in _m4_set([name],value) is chosen so that there is no
-# ambiguity with a set whose name contains a comma, and so that we can
-# supply the value via _m4_defn([_m4_set([name])]) without needing any
-# quote manipulation.
-

-# element is O(1), such that overall set creation is O(n).
