Let's get something out of the way, new guy. I am pretty
friendly. :)

The changes you are proposing simply build a static library.
Yes, I can do that, and perhaps I should have done that
before.

But your request was to build it directly to the
interpreter, that's what I said was tough. Even if the
makefile managed to link that static library to the Lua
interpreter, it would not be enough. You have to, as I said,
modify the interpreter to setup the package.preload table.

So, the user already has to modify lua.c and the Lua
makefiles. This kind of user is already pretty
knowledgeable. Add to that the small number of such users,
and you can see why it was left out.

Perhaps I should add support for raw sockets?  I already
distribute code that supports local sockets.  Shouldn't be
hard to do that for raw sockets.  Perhaps somebody else
already did it.  Could be useful for other stuff.

I have the impression you are trying to pick up a fight?
Sorry. I wasn't being sarcastic.
