So the problem with your patch is that you only check "errno == EINVAL"
without checking that "winerror == ERROR_DIRECTORY".

The other difficulty is that we should really get a second reviewer's
approval before merging it. And with Martin gone, and Andrew leaving...

Anyway, I'll put something together based on your patch and submit it
with MERGE. I *do* think it should go into 1.6, as it is a serious
regression in functionality.
