45f058844c Another tweak to the multiplication algorithm 
Reduce the formula to calculate mantissa so that we reduce the net
number of multiplications performed.

e69804d14e Use long wherever possible in mpa.c 
Using long throughout like powerpc does is beneficial since it reduces
the need to switch to 32-bit instructions.  It gives a very minor
performance improvement.
