This relates to the fact that Windows does not offer an easy way to
stat() correctly files which are more than 2GB, as the struct stat is
built with a 4-byte size field.
There has been some work on that lately (quoting Tom from a recent
mail):

However there is no way that a complex patch would get back-patched,
and that's what we were heading to in the latest discussions I recall
on the matter.
