Hello. I'm running 5.1-RELEASE.
I read the gcc man page. It is not clear what -O implys. Is -O equal to
-O1 or -O2? If I wish to optimize making does it make sense to add
CFLAGS=-O2 in the make.conf(5)?

-O is the same as -O1

Hi,
-O == -O1 (see `info gcc' - Invoking GCC - Optimize Options)
It is recommended not to use anything higher than -O
