Branches: MAIN
CVS tags: HEAD

Made Gforth compile on DOS. Cleaned up some minor parts in make binonlydist
Also renamed

unbuffered.fs -> unbuffer.fs
exceptions.fs -> except.fs
backtrace.fs -> backtrac.fs

in the CVS archive (do that in your gforth/CVS/Entries before checking out!!!)

If you want to make my life more easy, please refrain from using >8.3 file
names for vital parts.
