Log:
  MFC r350453:
  
  Add a CXXWARNFLAGS variable
  
  Some warning flags are valid for C++ but not C. GCC 8 complains if you pass
  such flags when building a C file. Using a separate variable for these
  flags allows building both C and C++ files in the same directory (such as
  the fusefs tests) under GCC.
