Test case

Hi,

This is forwarded from http://bugs.debian.org/741592

The printf documentation states that "%#x" prepends 0x for non-zero values
only, but the Wine implementation prefixes 0x for zero too:

$ cat t.c
#include <stdio.h>
int main()
{
  int val = 0;/* zero */
  fprintf(stdout,  "value=%#x\n", val );
  return 0;
}
$ i686-w64-mingw32-gcc t.c
$ wine32 a.exe
value=0x0

The resulting executable prints

value=0

when run on Windows.

Regards,

Stephen
