Fwd: util_expr_parce.c
Forwarded on behalf of Gregg L. Smith (his email bounced 3 times for
whatever reason).
-------- Original-Nachricht --------
Hi Stefan,
For some reason on Win we are falling through all the if(n)defs and are
getting these ugly warnings;
util_expr_parse.c(327) : warning C4273: 'malloc' : inconsistent dll linkage
C:\Program Files\Microsoft Visual Studio 9.0\VC\include\stdlib.h(601) :
see previous definition of 'malloc'
util_expr_parse.c(334) : warning C4273: 'free' : inconsistent dll linkage
C:\Program Files\Microsoft Visual Studio 9.0\VC\include\stdlib.h(600) :
see previous definition of 'free'
stdlib is being included in httpd.h since APR_HAVE_STDLIB_H == 1 in Win.
May I suggest looking for it in util_expr_private.h and define _STDLIB_H
there or any where/way you prefer.
#if APR_HAVE_STDLIB_H
#define _STDLIB_H
#endif
That rids us of the two ugliest warnings emitted from this parser.
Regards,
Gregg

That is an extremely ugly solution: stdlib.h uses "#ifndef _STDLIB_H"
internally, so this may negatively affect other plattforms or other
source files which include util_expr_private.h.
From reading util_expr_parse.c, I think something like
#define YYMALLOC malloc
#define YYFREE free
in util_expr_private.h could help. Please test this. Maybe it should
be surrounded by some suitable ifdef. Is _MSC_VER the correct ifdef
for visual studio?
Cheers,
Stefan
