Lua's type specifications and type management have improved in Lua 5.
You used to have to go through the code and change everything from
double to float (kids don't know they're born, in my day, etc. etc.) but
you only have change lua_Number now.

I think the only problem I have now is long, which is 64 bit on the PS2.
There are only a few occurrences in the Lua code, but nevertheless it
makes sense to remove them (for PS2). It would be nice if the longs were
ints or user defined. If in Lua long is assumed to be the same size as
int (i.e. the machines native word size) there seems little point in
using it at all.
