Sorry, I think I was just wrong about this and I don't remember at all any
more why did I write the above. Passing CXXFLAGS on configure command line
is perfectly possible and this is not something that changed in the last 3

You should be able to do
% $WXWIN/configure CXXFLAGS=-fno-omit-frame-pointer --with-cxx=11
without any problems.

Yes, definitely. And this does work, once again sorry for wrongly claiming
that it didn't.
