This is all messy.

If a program is written to a certain standard (as it should be) then
that will be clear from the README.  It should probe the compiler for
accepting --std=c++NN and then add that to CXXFLAGS.

FORCE_CXX_STD is for adding that via the wrappers for programs that are
deficient in setting it themselves (perhaps beause the upstream author
assumed that everything was like their local computer).

So yes, if the upstream is deficient this is needed, but it's not really
an approach fo rwarnings.
