I tried this slightly different program:

  #include <stdio.h>
  int main (int argc, char **argv)
  {
    char b[10];
    int ret = sscanf (" ", "%s", b);
    printf("ret = %d\n", ret);
    if (ret != EOF)
      { printf ("FAIL\n"); return 1; }
    return (0);
  }

Results:

  $ gcc -O -Wall sscanf-test.c && ./a.out
  ret = -1
  $ i586-mingw32msvc-gcc -O -Wall sscanf-test.c && wine ./a.exe
  ret = 0
  FAIL

So it seems the libc used with mingw behaves differently than glibc. I
guess it would be good if someone could run this program on a real
w*ndows box as well, to see if wine just is bug-compatible with windows.

I copied my binary to
http://www.lysator.liu.se/~nisse/misc/sscanf-test.exe if anybody dares
run it.

I have also seen failure of the t-printf testcase in this mingw32 cross
compiler + wine setup, but I can't reproduce that now.
