From 3d7fe3b822615cf1d11eeff1b97d8a5927a6d5b3 Mon Sep 17 00:00:00 2001 From: Andrew Knight Date: Sun, 2 Aug 2015 10:03:20 +0300 Subject: 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.

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]) -# then calls i([i],[i],[1],[2]). -m4_define([m4_foreach], -[m4_if([$2], [], [], [_$0([$1], [$3], $2)])]) - -m4_define([_m4_foreach], -[m4_define([$1], m4_pushdef([$1])_m4_for([$1], [3], [$#], [1], - [$0_([1], [2], _m4_defn([$1]))])[m4_popdef([$1])])m4_indir([$1], $@)]) - -m4_define([_m4_foreach_], -[[m4_define([$$1], [$$3])$$2[]]]) - -# m4_case(SWITCH, VAL1, IF-VAL1, VAL2, IF-VAL2, ..., DEFAULT) -# ----------------------------------------------------------- -# Find the first VAL that SWITCH matches, and expand the corresponding -# IF-VAL.
