Generally, at configure time, it is possible to supply startup values
of CFLAGS, CXXFLAGS, LIBS, and LDFLAGS that will propagate into
configure, and subsequently, the Makefile.  

For example, if you need a g++-specific flag on all platforms,
configure.in could have a test like this near the beginning, but after
the setting of the compiler name (so that GCC has been set or not):

test "$GCC" = "yes" && CXXFLAGS="-Wno-frobnitz $CXXFLAGS"
