   Registering a second unrelated type for the same extension should be
but is currently not acceptable. That should cause an error only if
boost build does not, for some reason, know which type to choose but
that is not always the case (see below for an example).

   Without this completely separate jam modules may cause conflicts when
used in the same project if they use source files of different types
with the same extension.

   We have several .jam modules modeling toolsets for different external
tools we automate using and some of them run into this
problem. E.g. internal LIB type is registered for the .lib extension but
one of the tools uses the same extension for its own libraries. These
libraries are built from their own sources and have nothing in common
with C/C++ libraries or their sources and so should cause no confusion.

   We currently quick-fix for this by making sure only one type is
registered for a single extension and making all other types derived
from this one but this is not a good long term solution as it forces one
toolset to know about others used in the same project.

   Should I add a TRAC item for this? Any chance someone more
knowledgable could take a look at this?
