Free-standing, optimized, FINALLY a gcc build of Dungeon with the DosGlk
patches.  This version has the CWSDPMI5 stub bound-in, so it is entirely
free-standing and does not require cwsdpmi.exe anymore.

This version fixes the problem with Matt Kimball's version trashing save
files by disabling character translation on all file output; plus, it is
a replacement for my Compatible WCL version (which is abysmally sluggish
even on a 5x86/133 machine), and should run fast enough.

djgpp is abominably big, and it took forever for me to get a minimal gcc
system set up on my computer.  But now that I have gcc, it will all fall
into place, and there shouldn't be any problems <crash> :}
