I don't like that we're starting to mix frozen code and non-frozen code. For example, `<wctype.h>` will now have to work with both the C++03 config and with the normal config. That's straying a bit away from the original design of the RFC, which aimed to make C++03 disjoint from the rest.

However, I understand the need for something like this in order to fix modules support. I think this can be tolerated if it only needs to be done in the C compatibility headers.
