i bet Michael would love to take a bite at this one.. :))
the gcc compiler chain has been around for a pretty long time now
(since the intruction of UNIX and the free software foundation)
and there has been a motorolla 68k cross compiler available way
before the Palm device was a twinkle in the eyes of the original
Palm engineers.
both compilers produce fairly efficient code.
you should not notice any significant difference between the two
binary outputs - however, it is always good to tweak with the -O?
flags :P
cheers.
