Not quite... clang is a relatively new thing. On v10.5.8 ppc64 'cc' is a
symlink to a real (well, Apple-flavoured) 'gcc-4.0'.
What about "... (clang on recent systems) and 'gcc' may be a legacy
llvm-gcc ..."?

I wouldn't be opposed to taking the default change into 1.3 as long as
we can still override it to a specific compiler.
But then again there's the question of why not doing it on Linux as well
now that we seem to compile under clang, we have cc -> gcc-4.7 on
openSUSE 12.2. Among our supported platforms only Solaris comes to my
mind where cc might be an incompatible proprietary compiler.
