Bah - I posted and committed a similar patch before I read this.

Not just cygwin, but windows in general.  And not just moving files into a read-
only directory, but deleting files from there as well.  Isn't it scary that 
Windows thinks everyone deserves root-like privileges?

I'm a little more comfortable with my patch - simply skipping the AT_CHECK if 
we know that the file will be created.

I can't speak for this one (I avoid mingw as much as possible, only cross-
compiling there), but it looks reasonable.  Please apply.
