Yeah, I noticed this, too.  One way to fix this would be to provide a
$(UCFLAGS) or something, which is specifically set aside for user-added flags.

This is particularly problematic for the ao library, as part of CFLAGS is a
define telling the library where to look for plugins, so if set your own
CFLAGS, it breaks things.

It would also be nice if the '-g' flag were always used.  AFAIK, there's no
reason not to include it when using gcc.

Yes, this would be nice.  Maybe make the --prefix value the default if the
others are not specified.
