Re: 64 bit Alien library with Lua5.2

[Fabio Mascarenhas <mascarenhas@...>]

I have no idea why the compiler is complaining about these casts, but
I commited a patch that removes them in favor of casts in the opposite
direction. Please tell me if it works, as I only have access to the
VS2005 x86 compiler and it was not complaining in the first place. :-)
