[New-bugs-announce] [issue31696] don't mention GCC in sys.version when built with Clang

[Benjamin Peterson]

New submission from Benjamin Peterson <benjamin at python.org>:

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.)
