Subject: [PATCH] Changes to make Tweak compile on Mac OS X (still as a
 Unix/curses application, of course). A couple of declarations and prototypes
 had to be moved higher up main.c (Apple's gcc installation is pleasingly
 pedantic, and I'm not quite sure how I got away with the previous code for so
 long!), and I've also had to arrange that Tweak can cope with curses being
 unwilling to allocate colour pairs.
