probably.  The particular issue here is that autoconf has a bias, making it
want to put -g -O2 when the compiler is gcc, and -g for other compilers.
So the -g is an assumption.  (The reason given for the choice is that gcc's
optimizer is good, and other compiler's are not - not true of course).

If you have set $CFLAGS, it overrides that behavior.  Most of the time,
settings for $CFLAGS should be for $CPPFLAGS (the -I and -D options) instead.
