Not quite: the "CPP" in CPPFLAGS does not stand for "C++" but rather for "C preprocessor". In the built-in rules, CPPFLAGS is part of the commands for both C and C++. The variable that is passed to the C++ compiler but not the C compiler is CXXFLAGS. So, if you want to pass a -D option to the C and C++ compiler, add it to CPPFLAGS.
