Yes - that combo is used for building ucrtbase.dll at the moment.

Ah, yes.

I guess calling this might be necessary later, once/if the functions that 
are in cpp.c are hooked up for building in vcruntime140. I currently 
didn't need those functions, so I didn't try to disentangle them from the 
rest of the msvcrt internal state yet. But it shouldn't be left here,

I'm not quite sure I understand your question completely.

If it's about the duplication of code; I guess one could keep the normal 
main.c and either split it into multiple files and just include some of 
them here, and disable parts of it with ifdefs (since this DLL shouldn't 
have most of the normal msvcrt internal state). If it's about the source 
file being in the msvcrt directory even though it's not used by the normal 
msvcrt, I guess that can be moved to the vcruntime140 directory as well.
