Hm, we have clang or gcc for CC. When I talk about 'system gcc' I mean:
[andreast at wandquad] /build/gcc/objdir_armv6/> gcc -v
Using built-in specs.
Target: armv6-undermydesk-freebsd
Configured with: FreeBSD/armv6 system compiler
Thread model: posix
gcc version 4.2.1 20070831 patched [FreeBSD]

Currently I have no clang installed since it does not build/bootstrap 
gcc-4.10.

This is my game.

It can either be gcc or clang.

:) nobody seems and nobody is happy with a half backed clang ;)

No experience here, sorry.
