Description
It appears that when one sets 'configure.compiler=clang', the compiler is invoked as 'clang', whereas it should probably be invoked as 'clang -std=gnu89' in order to maximize compatibility with GCC. Otherwise, clang compiles in C99 mode, which is subtly different than the C89 mode to which GCC defaults.
I have observed this to cause compilation failures with certain packages when using 'configure.compiler=clang'. Off the top of my head, teTeX is one, though I don't currently have logs available. They can be provided if necessary.

No, sticking with the default behavior makes more sense. Ports that don't compile should be fixed.
