The CXX command invokes the C++ compiler to compile C++ source
    programs. The syntax is as follows:

         CXX file-spec,...  +library-file-spec/LIBRARY...

    Qualifiers indicate special actions to be performed by the
    compiler or special input file properties. Compiler qualifiers
    can apply to either the CXX command or to the specification
    of the file being compiled. When a qualifier follows the CXX
    command, it applies to all the files listed. When a qualifier
    follows the file specification, it applies only to the file
    immediately preceding it.
