Boost-Build :

after attempting to use precompiled headers toghether with gcc 4.1.2, I
figured I might as well post my "findings" here.

Pre-4.2.0 gcc can't handle pch and anonymous namespaces in headers, ref:

This makes it virtually impossible to use pch toghether with e.g.
Boost.Lambda, Boost.Parameter to build programs with multiple translation

Perhaps a note of this could be added to the BBv2 pch docs?

Also - is it possible to disable pch using conditional requirements, making
the pch rule effectively returning a "null" target?
