No, please *don't* use the name CPPFLAGS when referring to C++.

CPP as a synonym for C++ might have some tradition in Microsoft-land,
but our tools are Unix-like, and CPP always referred to the C
preprocessor there, so CPPFLAGS are flags to apply when running the C
preprocessor alone (i.e. all the -I, -D and -U options that would
otherwise go into CFLAGS).

The correct spelling for C++ flags in a Makefile is CXXFLAGS, and the
C++ compiler is hold in the variable CXX.

Never trust an operating system you don't have sources for. ;-)
