Windows is known for having limitations in its former implementations
of stat(), and the various _stat structures they use make actually
that much harder from a compatibility point of view:

Nobody has actually dug enough into this set of issues to get a patch
out of the ground, which basically requires more tweaks that one may
think at first sight (look at pgwin32_safestat() in src/port/dirmod.c
for example).
