Could you please send this patch to the   patches at cactuscode.org
mailing list (and in general, could everyone please cc *all* patches
to that list)?  The other lists cactus lists (like developers@) are
now apparently configured to strip off the patches (at least I don't
see any patch with the message I got from developers@ to which this
is a reply), so without the cc to patches@, there's no way for anyone
other than the sender to see the patch!

stat()  and S_ISDIR  are in Posix, but are they in the non-Unix
platforms (Mac, Windoze)?  We may need a configure test to check this,
since otherwise cactus would fail to compile on systems where these
aren't defined.
