They certainly do something.  However it's so long ago that I can't remember 
the code and don't know for sure that what they do is correct.
There are two sets of inline functions there ... ones that act like casts to 
convert between float/double and the NSSwappedFloat/NSSwappedDouble forms 
(where the individual bytes are accessible) and the others which swap the byte 
order in the NSSwapped forms.  The real work is done by a combination of the

Is this just the compiler not liking objc stuff?
Why not just use a .m file extension?  CoreFoundation/Corebase code doesn't 
have to be implemented as C code ... it just needs to provide C functions as
