This rc uses the A-variants for the Windows functions in loadlib.c and
provides a new etc/luavs.bat that builds luac.exe (contributed by Mike
Pall). Please check that this script works; in particular, that it
builds luac.exe statically, so that this works fine:
	echo 'a=1' | luac.exe -l -p

Please take a look before we freeze it.  All feedback welcome.  Thanks.
