As a general principle for all such changes:

Macroization makes the code less readable, so should be avoided where not 
necessary.  In particular, where implicit conversions from integers to 
floating point will suffice to give the right floating-point value with 
the right type, use integers, so use integer 0 here, and make similar 
changes throughout this patch series whenever the floating-point constant 
has a small value (not -0) representable in int.  (Of course, explicit 
-0.0 does need to use a floating-point constant, not an integer constant.)
