Re: C compiler flags

The framework in devel/cpuflags catches this, which is in part why I
recommended it.  Simply install it and add the following to mk.conf:

.sinclude "/usr/pkg/share/mk/cpuflags.mk"
.sinclude "/usr/pkg/share/mk/optimize_gcc.mk"

COPTS?= ${DEFCOPTS} -pipe
CFLAGS+=-pipe

This will take care of everything--except, of course, those packages
which cpuflags doesn't catch (of which there have to be plenty,
depending upon architecture). ;)
