I investigated a bit regarding the first issue, and it looks like a cygwin
weirdness. The following patch works around the issue, but I have no idea
what's causing it in the first place (and why it doesn't happen on monobuild
for instance). It might even be a cygwin regression, this code hasn't
changed in years.
