Hi mcrosier, joerg,
For a few years now, FreeBSD has been carrying around a patch to recognize "CC"
and "clang-CC" as progname aliases for g++ mode. I would really like to get
this into upstreamed, to eliminate as many custom patches as I can.
I've just put the FreeBSD specific part between #if __FreeBSD__ delimiters, but
I suspect other OSes with case sensitive filesystems, and a historic usage of
CC as g++ aliases will also want to use this. Those can add additional defines
later on.
