Yep!

Yep!

I think it's found here:

ls -ltr /u/NetBSD/arch/i386/obj/tools/compat/include/

Empty, but there! Generated while "make" is running, after

include/.stamp:
        mkdir -p include/sys include/machine include/rpc
        @touch ${.TARGET}

in compat/Makefile is done, as ls -tr above suggests. 
But I've no idea, _how_ it's generated...
