	I agree that LightspeedC isn't as efficient as possible,  but to
compare itts execution on a Mac II to GCC's execution on a Sun 3 is unfair,
since the two machines have fundamentally different hardware designs.

	If you want to  make a valid comparison, run gcc on a Mac II running
A/UX. There's more to a comparison than just saying "The sun 3 has the same
CPU as the Mac II, and the same clockk speed (+/- 1MHz), but LightspeedC runs
slower on the Mac II, so it must be inferior."
