Subject: * data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
X-Git-Tag: v2.3b~447
X-Git-Url: https://git.saurik.com/bison.git/commitdiff_plain/fc3f467ff12133962ef69f58e60cb24fc29cc929?ds=sidebyside;hp=4d7bc38cdcb1fb457dfd34fdf7c81e507a002867

* data/yacc.c [(! defined yyoverflow || YYERROR_VERBOSE) && !
YYSTACK_USE_ALLOCA && ! defined YYSTACK_ALLOC && defined
__cplusplus && ! defined _STDLIB_H && !
((defined YYMALLOC || defined malloc) && (defined YYFREE ||
defined free))]: Include <stdlib.h> rather than rolling our own
declarations of malloc and free, to avoid problems with
incompatible declarations (using 'throw') C++'s stdlib.h.  This
should fix Debian bug 340012
<http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340012>,
