I doubt it, because I've verified that my changes produce identical binaries. The only difference now is because vers.o and ../btx/lib/crt.o are linked into the loader.sym binary in a slightly different order. By making some insignificant changes to loader/Makefile I've been able to verify that I still get the identical binaries (for all of sys/boot/i386/) with my changes, after I saw your first complaint in this thread.
