Windows has always been the easy one. The real question is "can we get a
version that works for Linux and FreeBSD? (and, ultimately, MacOSX, too). 
I'd love to have this function in the stdlib, but to date I've not seen a
decent version that always works under the *NIX OSes.  The moment I see
one (and they *can* be written, I just have looked into it yet), this is
definitely a routine to add to the stdlib.
