Re: Compiling Lua 5.11 w/ Visual C++ 2005 Express (fwd)

[Asko Kauppi <askok@...>]

Are you compiling it as C++?  Lua compiles both as ANSI C and as  
valid C++, it does _not_ declare its external functions extern "C" as  
most others do. This is by purpose.

You may use the etc/lua.hpp header, to have the extern declarations.
