Re: 64 bit Alien library with Lua5.2

[Fabio Mascarenhas <mascarenhas@...>]

Commited a patch to github to fix some of the problems below. I
remembered that Windows x64 was officialy unsupported; the latest
version of libffi has support for Windows x64, but I did not have a
machine to test this, so I just made Makefile.win64 so someone with a
Win64 machine could help me track down the bugs.

Fixed, libffi for Windows x64 does not define FFI_STDCALL.

These are very odd, because both lines have explicit casts. Could not
find anything on Google about this being specific behavior of the
cl.exe for Windows x64.

Seems like Lua 5.2 cut support for luaL_reg as an alias for luaL_Reg,
just changed it to use luaL_Reg.
