Need to define 'unix' to compile under OS X?

[Brian Schack]

I'm running GNU Emacs 22.0.90.1 (i386-apple-darwin8.8.1, X toolkit),
and I noticed a problem while running Gnus.  

Specifically, in nnmaildir-request-accept-article it makes a call to
the unix-sync function.  However, unix-sync is reported as undefined.

It seems the problem lies in fileio.c, where unix-sync is defined.
The definition of unix-sync is bracketed by #ifdef unix.  My guess is
that the symbol 'unix' is not defined when I compile under OS X.  To
test this, I reran configure as follows:

% ./configure ./configure --with-x CPPFLAGS=-Dunix

and things worked okay.
