The original architecture of go32.exe was small model to keep
Turbo-C's runtime from screwing with the rest of 640K memory, which
go32 was using to hold paging tables.  Had it been large model, I
would have had a harder time managing the 640K memory.

Note: A recent change (1.08 or 1.09) freed up about 4K of code space,
so some old fixes may now fit in debug32.  If I ever get around to
supporting gdb, this point will be moot.
