We have 54 source files using this "macro API."

Alternatively it's an indication of the need for better refactoring tools.

As Steve suggested in another email it might make sense to have a single
header define "macro API" defaults, that make sense for 99% of the
configurations. It would make it easy to adjust them en-masse instead of
rafactoring the changes across the 54 source files that use it.

Cheers,
Carlos.
