Thanks Randy

I would like to keep them in the Headers then. This is because I make
sure that the implementation includes the declaring header, so any miss-matches
are caught by the compiler.
And because these are all library routines exported to other modules. The important
thing is the API you linked with. If the API/parametrization change it must first
change in the header. The internal implementation is not documented only the external
black-box functionality is documented in these places.

I will think about it some more, but for now, if it's OK I would like to keep them
like submitted. In this particular library they make more sense to me in the header.

Boaz
