Hi,

I'm trying to compile OCL on my OSX Mountain Lion System using Macports to get
all dependencies. Currently Macports contains Lua 5.2 by default. However
building OCL against Lua 5.2 on my system results in the following error:

Apparently the defines of the missing identifiers have been moved into lua.c
and unreachable for OCL's lua-repl.c
