I would be pleased!

I still don't understand why this is relevant. Build systems should support CPPFLAGS. If they do not, the problem can be reported to the developers of those build systems. If the developers do not fix this problem, then we can manually fix it in individual ports by adding ${configure.cppflags} to configure.cflags and/or configure.cxxflags.
