Apple's macports developers had similar comments in their recommendations for
porting to Lion...

5) Building with a compiler that doesn't support newer __builtins
If your port uses MacPorts compilers rather than the default compiler, you may
run into trouble with string functions. You'll see errors at link time about
undefined __builtin_* functions. If this happens, you may want to compile with
-D_FORTIFY_SOURCE=0 to tell the headers to use unfortified versions which do
not use compiler builtins.
