You should probably remove all traces of 64 bit-ness on PS2. This will
save memory and possibly make it run faster. In Lua 5.0 I think you just
need to define LUA_NUMBER as float in your compiler environment, as you
know PS2 doesn't do hardware doubles. long is 64 bit on PS2 so change
all instances of this to int. Go into llimits.h and change all
instances.
