Global scope variables in the src

[Jim Mathies <jim@...>]

Hello,

I was curious if anyone could answer a question - how many variables
in the Lua src (including the io lib, etc) are declared global?  Is it
just
the Lua state variable or are there others?

This question relates to compiling the Lua src into a DLL on windows 
which can handle multiple threads at the same time.  DLL's, by default
don't make globals thread local.

Regards,
