FWIW, I don't think that we should attempt to work around actual
deficiencies in C++ compilers, but nor I do think that we should
accept code which is gratuitously non-portable. IOW, "requires an
ANSI-compliant C++ compiler" is OK; "requires g++" isn't.

Those gcc-specific switches should be removed from the Gmakefile; the
user can set CXXFLAGS when running configure if they want to add them.
