I think that is not a good idea.  Compiling with -O2 and with -O0
produces two very different programs, so doing that by default with
CVS sources means that we lose a lot of testing potential, as users of
the CVS version will be running a program that is utterly different
from what users of the released Emacs will see.  I expect quite a few
bugs to remain unearthed until the pretest stage.

I think the GCC feature whereby you can debug an optimized program is
a great benefit, since it lets you debug and test a program only once,
instead of doing that twice.  I'd hate to fail to use that with Emacs.
