For the cases where 32-bit protected mode and flat address space makes code simpler, DJGPP indeed produces faster code than BC. > Although, it produces > about the same code as Watcom from what I have understood, so the question > is, why does it have to be slower? 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.
