[M3devel] How to compile m3cc with -O0

[Rodney M. Bates]

Before I track this down laboriously, does anybody know right off hand where
to put the optimization flag -O0 for compiling m3cc?  There are dozens of
CFLAGS and similar in quake variables, make variables, environment variables, etc.,
getting passed all over the place.  Naive replacements of "-O2" by "-O0" so
far aren't getting through to the compilation.
