Well, I didn't say bjam can do anything. I would love it if printed out
money ;-)

Here's a Jamfile for the signals library that does what the makefile you
posted does, and slightly more as it also works for other compilers other
than msvc.

The only change is the addition of the "stage bin-stage..." portion. There
are some differences in the output from the arrangement, and compsition of
the name of the files. The stage declaration tags this in alphabetical order
so the names wont match what your header is expecting. I use alpha ordering
because it's a more stable arrangement that doesn't change from library to
library. But you could easily change the header to handle this difference

Here's the script with the resulting list of libraries it generates on my
system, RH73-Linux, with gcc and gcc-3.2, and stlport 4.5.3...
