[Salvatore Domenick Desiano]

o > * you can add -O -g if the port requires it with just:
o > configure.universal_cflags-append	-O -g

o Why isn't -O (equivalent to -O1) used by default?
o 
o It is regarded as stable by Apple (since it is in the tech note)
o and is better than the default -O0 (no optimization).

I guess it's unclear to me as well why we wouldn't follow TN2137 by 
default.
