The boost/build/v1 common-names rule computes a toolset name of "bcb56" when using borland-5.6.4-tools. The boost/config/auto_link.hpp file does not discriminate between bcb5.5 and bcb5.6, using "bcb". Auto link therefore fails.
It was done deliberately that way, because historically we've only had one Borland toolset, so the names were not versioned.
I have made the following local fix to auto_link.hpp, since to me the common-names toolset name computation seems to be self-consist across toolsets.
Whould it be possible to fix either auto_link.hpp or the boost build v1 common-names rule - whichever makes more sense.
What we really need to do before the next major release, is figure out how to get the compiler version into bjam so that the name mangling doesn't depend upon the toolset name, that way the bjam names and the auto_link names could always be in synch, Rene? John.
