That is asking for trouble. "CFLAGS" is used by a lot of software
packages in very weird ways. MySQL e.g. puts "-DUNIX" or something
like that in there. If you set "CFLAGS" the wrong way its build will
fail. You will find the details burried in NetBSD's PR database.

If you want to enable custom compiler optimisation use the
"CPU_CFLAGS" settings, please.

"pkgsrc" already allows to switch between 32 bit and 64 bit via the
"ABI" setting. We should only agree what the default for
Mac OS X Snow Leopard is and deal with the problems of "ABI=64".

        Kind regards
