Ok sure, let's make only undef an error, not all other warnings. Then the behaviour will also be the same as on MSVC.

It didn't cause any other errors for the huge HPE codebase. Only undefined macros. I don't believe the preprocessor has so many warnings anyways.
So -Werror should be fine.

Hi Derek,
-Werror. Make all warnings into errors.
Should here be that only treat undef warning as error?
Thanks,
Bob

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.
