Any help with this would be appreciated. Any properly written Makefile should provide the user a way to specify things like CXXFLAGS in the environment or when invoking make. For autoconf based packages you can create a config.site file with the desired settings. If that's not enough you can create a wrapper script for g++ and put it ahead of the actual g++ in the PATH. Alternatively, you could edit the gcc specs file. But these are both horribly ugly solutions -- the various *FLAGS are meant to be the domain of the user, not the package, so it's a bug in the package if they can't be reasonably set somehow; editing a bunch of Makefiles should never be necessary.
