Subject: Some distutils work:

- Add better support for C++ in numpy.distutils. Instead of munging the
  C compiler command, build_clib and build_ext call the new
  Compiler.cxx_compiler() method to get a version of the compiler suitable for
  C++ (this also takes care of the special needs of AIX).
- If config_fc is specified in the Extension definition, merge that info
  instead of replacing it (otherwise, the name of the Fortran compiler is
  overwritten). This is done at the key level (ex., compiler options are
  replaced instead of appended).
- clean up compiler.py a bit
- clean up linking in build_ext
