Well, 'cc' is there for the same reason that 'gcc' is there, but with the knowledge that gcc no longer has a monopoly on compilation. cc can be the sun compiler, clang, gcc, or any other compiler out there.

Yes, we want to have *specific* values used as defaults in portconfigure.tcl, but we use 'gcc' as a fallback for the default if we can't determine the XCode version (such as on puredarwin, BSD, etc).  This fallback should change to 'cc', but I wanted to test the waters first to determine if we should remove the 'gcc' option at the same time or just leave it in there for compatibility.
