Comment # 2 on bug 1223169 from Richard Biener

The odd thing is this is behind

#ifdef HAVE_WORKING_STAT
# define FIND_FILE0_DECL struct stat *st
# define FIND_FILE0_ARGS st
#else
# define FIND_FILE0_DECL uint64_t id, const char *path
# define FIND_FILE0_ARGS id, path

but yes, if !HAVE_WORKING_STAT the code is broken.  So the question would
be why !HAVE_WORKING_STAT - we're expecting this only for __MINGW32__.
