Unless I'm missing something, those shouldn't be needed - I deliberately disabled std lib configuration when __cplusplus isn't set as it makes no real sense in C mode?
Agreed. But you do have checks for __cpluscplus in some of the other config/stdlib header files so I made those patches to conform. Maybe you could now remove those others, and just ignore those patches I sent.
No, the point is that the compiler and platform configuration headers are included in C mode, but the C++ std lib ones are not (as there's no point).
Attached are two more, which are relevant, and one which is a cosmetic spelling change which confused me when I first read it and means almost the opposite of what you meant to say in a comment. These are the last I found.
Thanks, applied, John.
