The IUP binaries (esp. imlua51.dll) apparently include hardcoded,
bytecode-compiled Lua files. And they do not properly check for
returned errors from luaL_loadbuffer().

So what happens is that (obviously) loading the bytecode fails
(it's incompatible), the errors get ignored and the initialization
of the library fails with the above message.

Solution: file a bug against IUP.
