Okay, it makes sense to only do the conversion for a successful return code.

Should it test for both a zero return code and a non-null pointer?  I
don't know if there are any cases where passing a null pointer is
legal.  The standard doesn't seem to explicitly forbid it.  z/OS
returns -1 and sets errno to EFAULT when stat() is given NULL, but
this patch should be able to be used on any platform.
