[New-bugs-announce] [issue22110] enable extra compilation warnings

New submission from Charles-François Natali:

The patch attached enables -Wsign-compare and -Wunreachable-code if supported by the compiler.
AFAICT, mixed sign comparison warning is automatically enabled by Microsoft's compiler, and is usually a good thing.
It does add some warnings though.

As for unreachable code, it's also usually a good thing, since it can be a source of bugs. Note that it's not enabled in debug mode, since in debug mode the code paths aren't the same.
