Re: LuaBinaries - why so many Win32 versions?

[Stefan Sandberg <keffo.sandberg@...>]

Lua linked to crt X can only load modules linking to the same crt X, 
anything else is wrong(even if it manages to run fine for a bit, it's a 
timebomb).
This has nothing to do with lua nor luabinaries, but the fact that 
windows is an os based on binary distribution,
unlike *nices which are based on source.

Just deal with it, you can't get around it...
