Yes, it would be possible to do the same thing for CPPFLAGS. However,
you really need to combine the values. If you assume you don't know
anything about the current value of CPPFLAGS, this might get tricky -
you might cause build failures if you honor CPPFLAGS too much.

You shouldn't do this - you do need to consider the values in the
Makefile as well. If you think you need both, you should modify
configure.in appropriately.
