Note that this requires compiler patching, because abs() is internal  
(it can be used in constant expressions). I would personally argue to  
do away entirely with the "treat currency as a floating point type on  
i386 so it can use the 80x87", and instead map it implementation-wise  
to int64 like on all other platforms. You may lose a bit of  
performance, but you'll gain consistency. And you won't need hacks  
like this (which, as mentioned before, only solves one particular use- 
case, and so I'm not very much in favour of doing this).
