Fleshing it out.  I just started actually using clang yesterday --

Maybe. :-)  If your project doesn't use any GCC compiler flags or
language syntax that clang doesn't support, yes.  Just set CC=clang
and CXX=clang++, and you should be good to go.

And it's fast; I got a 5% reduction in XEmacs build time on a MacBook
Pro, which is big considering that 70% of the build is compiling Lisp
to bytecode and running tests.  At a guess, it compiles C about 25-30%
faster than GCC 4.4.  I don't know yet if the produced XEmacs feels
any faster.
