Subject: APR_CHECK_SIZEOF_EXTENDED issue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
Content-Disposition: inline

The current APR_CHECK_SIZEOF_EXTENDED includes stdio.h before doing
anything specified by the macro caller.

dnl APR_CHECK_SIZEOF_EXTENDED(INCLUDES, TYPE [, CROSS_SIZE])
[snip]
[AC_TRY_RUN([#include <stdio.h>
$1
main()
{
  FILE *f=fopen("conftestval", "w");
[snip]


Say someone needs to do something like this:

APR_CHECK_SIZEOF_EXTENDED(#define _FILE_OFFSET_BITS=64
#include <sys/types.h>, off_t [, whatever])

or whatever #define that may change the default behaviour and
consequencs of including stdio.h first.

Wouldn't it be better if we switch to something like:
[snip]
[AC_TRY_RUN([$1
#include <stdio.h>
main()
{
  FILE *f=fopen("conftestval", "w");
[snip]

and permit this kind of behaviour too?
