This is something that would also need to be addressed in kmp.h. 

Does this versioning have a correctness implication, or is this a performance optimization?
In the latter case, from my perspective, a viable approach would be hardcode the endianess, if the two macros are undefined.

It's your choice to fix it as part of this patch or whether you prefer to fix it in a separate pr:)
