I was one of the principal beaters of this topic.

My net postings have been cleaned up, enhanced, and submitted to
SIGPLAN Notices (no idea yet on publication date).  They are also
available as a technical report from my department's SoftLab (software
research laboratory).  You can either watch SIGPLAN for J. Coggins and
G. Bollella, "Managing C++ Libraries" or e-mail for a copy of our
technical report (which will soon include an addendum with some
further techniques) to Pam Payne, Softlab Coordinator at
softlab@cs.unc.edu or to the address below. 

The organization scheme I descibed requires no preprocessor hacks,
includes headers once and once only, imposes minimally on the program
development process, and is still working well with VERY little
maintenance required.  In fact, we have extended it recently to handle
compilations of my research library for multiple architectures (Sun3,
Sun4, Vax780) and are preparing to incorporate RCS support directly
into the management structure. (These points will be described in the
addendum to the SoftLab TR).
