bug, -0 is not evaluated correctly.

[David Jones <drj@...>]

There is a minor bug in the way that the constant -0 is evaluated.  
Obviously this only applies on platforms using something like IEC 60559 
arithmetic (aka IEEE).  Like Mac OS X, which is what I use.

The lua statement "print(1/-0<0)" prints "false".  Compare that with 
"x=0;x=-x;print(1/x<0)" which prints "true".

Would you like me to look into a patch?  I haven't investigated where 
this goes wrong at all yet.  Thinks... perhaps it is not possible to 
correct this without non-portable code.

For the record I'm using

Lua 5.0.2  Copyright (C) 1994-2004 Tecgraf, PUC-Rio

on Mac OS X 10.3.7
