I *think* I've solved this. I changed my dll project to build a lib
file instead, which generated a new lua53.lib file that was 926 Kb
instead of 2 kb. That allowed the linking to complete, but linking lfs
created an lfs.lib not a dll because of a different error. I rebuilt
my lua53.dll file as well and the DLL built. The final lfs.dll file is
171,008 bytes. That seems large but I don't know any better. Will try
it shortly...
