For the cases where 32-bit protected mode and flat address space makes
code simpler, DJGPP indeed produces faster code than BC.

One reason is that GCC is a portable compiler whereas Watcom is hand-tuned
to the x86 architecture. The other reason is that GCC is multi-pass
compiler (i.e., it invokes several passes in different programs), which
slows it down somewhat.
