Changes between 1.19-6 and 1.21-8
	- cosmetics...
	- bison.cc, bison.h : generalize MSDOS to WINDOWS and alike.... 
	- bison.cc, bison.h : WINDOWS: simulate alloca with malloc, via macro 
Changes between 1.19-6 and 1.21-7
	- bison.cc, bison.h : use macro to simulate goto in yyparse. for sun c++.
	- bison.cc : mismatch in #if between YY_USE_CLASS and compatibility just
        before including #define tokens. added a #endif and a #ifndef YY_USE_CLASS
	- generate enum to replace enventually the static const
	- output.c, files.c : manage to put #line in generated code, such that the generated code is correctly indicated in the output file. 
Changes between 1.19-5 and 1.21-6
	- bison.h : parameter name forgotten in 
	'virtual void YY_@_ERROR(char *) YY_@_ERROR_BODY;' so inline cannot use
        the parameter. just add the name 'msg' as parameter.
Changes between 1.19-3 and 1.21-5
	- send on internet as patch 5
	- patch according to release 1.21 of bison :

	- Notes.txt : creation of this file, with mail transaction

	*files.h reader.c output.c : backquote not quoted in filename (dos). created function -> quoted_filename().
	*reader.c : (int)0 passed to set_parser, instead of NULL, caused bug on DOS 16bit. Corrected in  parse_define().
