+Low-level file handling
+~~~~~~~~~~~~~~~~~~~~~~~
+The functions in osfcn.h are unavailable when compiling under C, as it's a
+C++ header. Therefore they have been implemented here.
+
+Now, why have I done it this way?
+
+The definitive API library for RISC OS is Jonathan Coxhead's OSLib, which
+uses heavily optimised ARM assembler or even plain inline SWI calls for
+maximum performance and minimum runtime size. However, I don't want to make
+LIBTIFF need that to survive. Therefore I have also emulated the functions
+using macros to _swi() and _swix() defined in the swis.h header, and
+borrowing types from kernel.h, which is less efficient but doesn't need any
+third-party libraries.

+ * They make no calls to the THINK C "unix" compatibility library. Also,
+ * malloc is not used directly but it is still referenced internally by
+ * the ANSI library in rare cases. Heap fragmentation by the malloc ring
+ * buffer is therefore minimized.
+ *
+ * O_RDONLY and O_RDWR are treated identically here. The tif_mode flag is
+ * checked in TIFFWriteCheck().
+ *
+ * Create below fills in a blank creator signature and sets the file type
+ * to 'TIFF'. It is much better for the application to do this by Create'ing
+ * the file first and TIFFOpen'ing it later.
+ * ---------
+ * This code has been "Carbonized", and may not work with older MacOS versions.
+ * If so, grab the tif_apple.c out of an older libtiff distribution, like
+ * 3.5.5 from www.libtiff.org.
