If public headers only contain public symbols the process is
self-bootstrapping - the set of symbosl to make local on unix are all
these nm shows up but that aren't in the public headers.

You can't unfortunately avoid the hedaer markup on windows, and it is
needed on unix only if there is no spearation of headers into
private/public (or there is no easy #ifdef to leave them out)
