We probably shouldn't encourage such poor design ;-)

The proposed patch generates a whole mass of ifdefs all over the place.
If it's going to be done move all the functions in question together
somewhere logical and give them a single ifdef or a file of their own.

It also doesn't appear to be dropping all it should - why can't you
simply not compile in groups.c for example ? If you can't then it says
the patch is far from complete at this point.
