VFR successfully compiles if we forget to include a header that defines a macro. In that case the HII option was hidden when it shouldn't be just because the macro was used but not defined.
The behaviour is totally intended by the C/PP standard. When a macro is undefined it evaluates to 0. GCC, MSVC and Clang have warnings to catch this type of mistake. With this commit we enable this warning and make it a compiler error.
