FWIW, I've bootstrapped several times since June 12, and had no
problems.  But I use neither MSYS2 nor MinGW64.

Please show your epaths.h.

Also, how did you configure Emacs, exactly?  What was the configure
command line?  Did you run autogen.sh after updating.

Are you building from outside of the source tree, or in some
build-specific subdirectory of it?

Follow the error messages, I'd say.

I don't know (that's part of the problem), but the warning come from
lread.c:load_path_check, I think.  (I just grepped the sources for
"Lisp directory", and that was the only hit.)  Likewise, the warning
about arch-independent data dir comes from callproc.c:init_callproc.
Setting a breakpoint in these locations and looking athe backtrace
should get you started.
