Set the maximum warning verbosity according to C and C++ compiler
used. Currently supports g++ and gcc.
The compiler options are always added CFLAGS and CXXFLAGS even if
these are overidden at configure time. Removing the maximum warning
flags can be removed with --without-maximum-compile-warnings. For
example:
./configure --without-maximum-compile-warnings CFLAGS= CXXFLAGS=
