Don't you also need to set CPPFLAGS too, in general?  Otherwise how
will programs that run the preprocessor get the correct values for
symbols like LONG_MAX?

It does sound pretty inconvenient.

I use something like CC='gcc -m64' CXX='g++ -m64', but that's not much
better, and probably also has flaws.
