Well, that may not be needed entirely, AFAIK, according
to the ANSI C standard, only names beginning with two underscores 
or names beginning with with one underscore followed by a capital 
letter are reserved for the internal use of standard libraries. 
/Normally/ you should be able to use names that begin with a 
single underscore followed by a lowercase letter without problems.

The problem with the predefined _G on MacOSX simply boils
down to a conflict of lua C code with the ANSI standard. But,
using something like _g, or better still, _lua_g, is acceptable
and does not violate tthe C standard.
