The logic behind picking CC hasn't been changed (yet).=20

On some platforms (Linux, Darwin) we let the user and ./configure pick =
which C compiler to use, and don't attempt to second guess them. We're =
already using this for things like running the code base through the =
Clang static analyser.

On other platforms (Solaris, IRIX, AIX, HPUX) we override configure's =
choice because "we know best". In theory we should also be overriding =
the flags we pass so that they match the compiler choice, but it's =
entirely possible we get this wrong.

Cheers,

Simon.
