Why not?  I've never built a "special" compiler for any development
work, and am very likely to use the default compiler installed on
my YDL system (which could likely be a G5) for building any
embedded PowerPC software.

What do you mean by "won't work"?  The compiler simply refuses
or builds for a POWER4 because we don't have the proper -mcpu
flags?

Thanks.
