* backends: smt2: use $(CXX) variable for compilerSean Cross2019-09-081-1/+1
| | | | | | | | | | | The Makefile assumes the compiler is called `gcc`, which isn't always true. In fact, if we're building on msys2 or msys2-64, the compiler is called `i686-w64-mingw32-g++` or `x86_64-w64-mingw32-g++`. Use the variable instead of hardcoding the name, to fix building on these systems. Signed-off-by: Sean Cross <sean@xobs.io>

| | | | | | | | | | | | | | | | | | o Not all derived methods were marked 'override', but it is a great feature of C++11 that we should make use of. o While at it: touched header files got a -*- c++ -*- for emacs to provide support for that language. o use YS_OVERRIDE for all override keywords (though we should probably use the plain keyword going forward now that C++11 is established)
