freebsd-dev/contrib/llvm/patches/patch-r263048-clang-r203624-fix-CC-aliases.diff

Pull in r203624 from upstream clang trunk (by Hans Wennborg):

  Be case sensitive when determining driver mode based on argv[0] except on Windows

  This narrows the impact of r188833 after Dimitry pointed out that it's good to be
  able to tell the difference between 'cc' and 'CC'.

Introduced here: http://svnweb.freebsd.org/changeset/base/263048
