This is the conclusion I came to.

I am not sure which is less painful. My gut says it would have to be added to a lot more places in gcc than newlib. It is easy to solve in newlib. Although it seems more correct to add it to GCC.

I suppose I should restart this thread over at GCC to get more opinions.

I think the GCC support is incomplete since it offers builtin defines for the limits and the constants (e.g. #define __INT32_C(c) c ## L).
