RE: LuaBinaries and the RTL DLL for 5.2

["Antonio Scuri" <scuri@...>]

  Just to clear things. LuaBinaries will still contains binaries for all
platforms it supports today. I mean the "dll9" package for instance is the
DLL generated by VC9 depending on msvcr9.dll, the "dll8" by vc8 dep. on
msvcr8.dll, and so on.

  The discussion here is only about the executable, that we distribute only
one. So we have to choose the DLL it will use. And since Lua for Windows
uses our executable then this decision affects LfW users.

  Once thing that I forgot is that I don't know how to build 64 bits
executables in Windows using gcc, only with vc8 or vc9. So the 64 bits
executable package will still have to use one of those. For now is not a big
deal because LfW only distributes 32 bits. Any clues on this?

Best,
scuri
