gnu1987/bison-1.21-8/ChangeLog

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 :

	* Implement `-l' option.
	* getopt.c: Set flag `nolinesflag'.
	* reader.c (copy_definition, parse_union_decl, copy_guard, copy_action)
	Obey that flag; don't generate #line.
	* output.c (output_parser): Discard #line's when copying the parser.

	* bison.simple: Correct number in #line command.
	(yyparse): Call YYABORT instead of YYERROR, due to last change in
	output_ltype.

	* reader.c (parse_token_decl): Ignore commas.

Sat Jun 25 10:29:20 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

	* reader.c (output_ltype): Make YYERROR yacc-compatible (like YYFAIL).

Fri Jun 24 11:25:11 1988  Richard Stallman  (rms at sugar-bombs.ai.mit.edu)

	* getargs.c (getargs): -t sets debugflag.
	Eliminate upper case duplicate options.
	* output.c (output): If debugflag, output `#define YYDEBUG'.

Thu May 26 06:04:21 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

	* allocate.c (mallocate): New name for `allocate' (which loses in VMS).
	Calls changed in LR0.c, conflicts.c, symtab.c, new.h.

	* getargs.c (getargs): If argv[0] is "yacc", set fixed_outfiles.

	* conflicts.c: Declare alloca.
	* reader.c: Declare realloc.

Thu May  5 14:36:03 1988  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

	* bison.simple: Conditionalize most refs to yylsp on YYLSP_NEEDED.
	* reader.c (copy_guard, copy_action): Notice if `@' is used.

	* bison.simple: New variable yynerr counts calls to yyerror.

	* lex.c (lex, case '='): Update lineno when skipping a newline.

	* reader.c (parse_expect_decl): ungetc the char that ends the number;
	don't read any further.  This handles multi-line comments right
	and avoids incorrect lineno.

	* warshall.c (RTC, TC): Cast ptrs to char *, not unsigned, for arith.
