[Dimitry Andric]

Author: dim

New Revision: 263048
URL: http://svnweb.freebsd.org/changeset/base/263048

Log:
  Repair recognition of "CC" as an alias for the C++ compiler, since it
  was silently broken by upstream for a Windows-specific use-case.
  
  Apparently some versions of CMake still rely on this archaic feature...
