changes needed to build bison-1.33-win32 using Visual C++
command line tools only.




CHANGED FILES:

src\files.c

	a local variable was declared 'const', but then used
	as non-const. fixed to use a temporary non-const.

src\state.h

	the macro 'CORE_ALLOC' subtracted 1 from zero when dealing
	with unsigned integers. this caused a compilation warning on
	win32, but may have resulted in huge allocations on other 
	systems. proper fix should be implemented by original
	author (Akim Demaille  <address@hidden>), but meanwhile, assume 
	CORE_ALLOC(0) means no elements	wanted, rather than 'allocate 
	entire virtual memory area, and then some more'.

src\system.h

	<io.h> is needed on Win32 systems for the operation of 
	'access(filename,mode)'. changed the check for 'MSDOS'
	to include '_WIN32' as well.

lib\quotearg.c

	code assumes that 'iswprint' cannot be defined if HAVE_MBRTOWC
	is not defined. i am unsure of the correct way to fix this,
	since defining HAVE_MBRTOWC is not correct for Win32, and
	Win32 has iswprint defined. changed code to only define iswprint
	if it is not already defined, which should be safe on all systems.



NEW FILES:

win32\config.h

	config.h for Win32 systems. if you use a compiler other than
	visual C++, you may have to tweak it.

win32\makefile

	makefile for MS' nmake program. to build bison 1.33-win32,
	just type nmake when in the 'win32' subdir.

win32\w32bison.c

	contains a modified main() to ensure that bison looks for
	bison.hairy and bison.simple in the place given by the
	environment variable 'BISON'.
