Maybe I should provide a few more details about our "desired
workflow". Our top-level Jamfile is here: 

<http://cvs.sourceforge.net/viewcvs.py/adobe-sourc
e/adobe-source/Jamfile.v2?rev=1.1&view=markup>

We have been using aliases to force desired targets to build,
including some boost libraries on which our own library depends
(thread, signal and filesystem). After issuing a call to, say, bjam
gcc at the top level, for example, we find the boost filesystem lib
at: 

./third_party/boost_tp/boost/bin.v2/libs/filesyste
m/build/gcc/debug/link-static/threading-multi/libboost_filesystem.a

Now we can provide our library clients with an IDE-based project that
statically links against the boost filesystem lib by adding:

./third_party/boost_tp/boost/bin.v2/libs/filesyste
m/build/gcc/debug/link-static/threading-multi/

to the list of library search paths (e.g. with -L). We also must tell
the IDE that we will be linking against boost_filesystem (e.g. with
-l). This all works fine with BBv2 from 1.32.0.

In CVS BBv2 the built filesystem library is now named

libboost_filesystem.a.1.33.0

Unfortunately, some platforms, such as the gcc-based XCode IDE for
darwin, will not recognize artifacts as libraries unless they have a
specific extension, so our IDE-based projects that try to link against
the boost libs no longer work.

I don't claim that our Jamfiles our the best possible--any suggestions
for improvement are welcome. But the particular issue that I am
interested in solving in this thread is the suffix problem. Perhaps I
should be avoiding aliases?
