Sorry if this is the wrong group, but is there some common library of
routines to manipulate 64-bit ints on a machine that only supports 32bit
ints native?  ie, I have these "wides"  that are a 

typedef struct {  
   long hi; 
   unsigned long lo;
} wide;

I have routines (easily written myself) for addition, subtraction, negate,
and conversion to and from longs.

I need routines for bitshift, multiply, and divide.
Multiply should take two longs and return a wide.  Divide should divide
a long into a wide, and bitshift should be able to shift a wide n bits,
either way (+ for right, - for left)

So, is there any refined code out there?  Something new for the standard?
