Hello Dan,

Neither.  At least if you are a package author, then you shouldn't pass
CFLAGS to the C++ compiler nor CXXFLAGS to the C compiler.  The user
ought to be able to choose different compilers (even from different
vendors) for each; also, there are compiler suites where the C and the
C++ compiler have a different supported option set.

CPPFLAGS are passed to both compilers, however, as they both make use of
the preprocessor.

Cheers,
Ralf
