Hm.. This should work.. I can easily delete the current dir in CygWin with the M$ Explorer, but do get a "permission denied" when I try it in cygwin. (If I do this:
$ cd
$ mkdir test
$ cd test
In explorer, delete p:\cygwin\home\RonaldLandheer\test
$ cd ..
I end up in ~/test/..

It would seem the _current_ process can't kill its own directory..
Would it be possible to fork, go a dir lower and destroy it from there? (Haven't tried it yet, but I'd expect the same results)

Greetz!

Hmm. It looks to me like this should fail, even under Unix. Once you've chdir'd
into test, it no longer exists at the current directory level. Shouldn't the
sequence be

mkdir("test");
chdir("test");
rmdir("../test");

Of course, even this will fail under Windows because Windows won't allow the
current directory to be deleted if it's in use by any process.
