    When built with clang, Python reports that it was built with something like "GCC 4.2.1 Compatible Clang 4.0.0 (tags/RELEASE_400/rc1)". This is because clang pretends to be GCC 4.2.1 for the purposes of the __VERSION__ preprocessor macro. We should use __clang_version__ when clang is being used.

    (Possibly we should simply use the first line of "$CC --version" as the compiler version of record rather than writing preprocessor tests in getcompiler.c.)
