Paul Eggert 5bab03fcf8 Rename struniq to uniqstr, to avoid collision with <string.h>. 2002-12-11 05:20:31 +00:00
Paul Eggert 996b1c7e8c * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__, 
since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename.  This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
 2002-12-09 04:48:38 +00:00

Fix Debian Bug 102878.
 2002-12-07 08:09:17 +00:00
Paul Eggert 050931e3f9 (Invalid inputs): No longer `expecting ";"

 2002-12-07 05:50:45 +00:00
Paul Eggert 4f21fffe7e (yy_reduce_print): Don't assume that yyrline[yyrule] promotes to int;

consistency with the other scanner helper functions.
 2002-12-01 02:37:56 +00:00
Paul Eggert 6ba5559289 Type clashes now generate warnings, not errors, since it 
appears that POSIX may allow some grammars with type clashes.
 2002-11-30 09:52:42 +00:00
Paul Eggert e927351156 (grammar_current_rule_check): Warn about

Paul Eggert 0af19cd0c1 lib/main.c, lib/yyerror.c: New files. 2002-11-30 09:10:20 +00:00
Paul Eggert 38a92d500a Emphasize that yylex and yyerror must be declared before being used. 
E.g., one should typically declare them in the prologue.  Use GNU
coding style in examples.  Put "const" consistently after the type it
modifies.  Mention that C99 supports "inline".  Mention that yyerror
traditionally returns "int".
 2002-11-30 07:42:37 +00:00

All uses changed.
(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove.  All uses changed.
The name "yycontrol" violates the name space rules, and this stuff

 2002-11-27 18:33:18 +00:00

Paul Eggert 580043087e * lib/argmatch.c, lib/argmatch.h: Sync with gnulib. 
Avoid use of <assert.h>, as the GNU Coding Standards hint that one

anyway it's one less thing to worry about configuring.

and it shouldn't hurt on other compilers.
