2 weeks turned into 7 months.  Sorry for not replying to this thread
sooner.  I like Paolo's suggestion of documenting that it is acceptable to
change the default CXXFLAGS if the package author doesn't like autoconf's
default, without penalizing the user's ability to specify better arguments
than the package default.  How does this wording look?
