This code causes a crash in the compiler. ( I'm pretty sure it's valid code
also )

[DllImport( Lib, CallingConvention = CallingConvention.Cdecl, EntryPoint =
"luaL_error" )]
private static extern void L_error( IntPtr state, string format, __arglist );

public void L_Error( string format, __arglist )
{
    L_error( state, format, __arglis );
}
