Good catch on mkostemp, and the many new tests are always welcome.

As far as I can see (I didn't study the W32-specific bits),
this all looks fine.  I confirmed that it builds and all tests
pass when used with coreutils on Fedora 12.

If you can push those soon, I'll include them in a coreutils
snapshot tomorrow, leading up to a release on Tuesday or Wed.

Thanks!
