Currently, -fsigned-char and -funsigned-char are only documented as C language options, although they work for C++ as well (and Objective-C and Objective-C++, I assume, but I have not tested this). There does not seem to be a place for this kind of options in the manual.
The options -fshort-enums and -fshort-wchar are documented under code-generation options, but this seems to be a bit of a stretch because (at least for -fshort-wchar), these too seem to be more about front-end behavior. What would be a good way to address this? Thanks, Florian
