Hi,
As part of making clang the default system compiler for FreeBSD, it
turned out there are quite a few programs out there, which assume 'CC'
is a C++ compiler. In FreeBSD, we always had a link from /usr/bin/g++
to /usr/bin/CC for that purpose.
Clang already recognizes a number of different program names, and
deduces the correct behaviour from them. I would like to propose adding
'CC' and 'clang-CC' to the list.
The only possible issue I can see with this is with case-insensitive
filesystems, but even those usually preserve case. (And then you would
not be able to have both 'cc' and 'CC' in one directory anyway...)
