not "_STL" as my program), because STLPORT_ROOT was not set. Instead I set
STLPORT_PATH, as required under Windows. Changing STLPORT_PATH to
STLPORT_ROOT and re-builduing boost-signals fixed all undefined references.
Thanks for your help!
This brings me to another point: I think it is extremely inconvenient to set
STLPORT_ROOT under Linux and STLPORT_PATH under Windows as it is a source for
errors like my one. Why couldn't you change boost-signals, so that
STLPORT_ROOT is used on all platforms (like BOOST_ROOT, for example)?

on the GCC side, but STLPORT_ROOT is marked deprecated. Looks like you can
use STLPORT_PATH in the same way on Linux and Windows:
path ?= $(STLPORT_$(version)_PATH) ;
path ?= $(STLPORT_PATH)$(SLASH)STLport-$(version) ;
path ?= $(STLPORT_ROOT) ; #<< For backward compatability.
This is more of a Boost.Jam/Boost.Build question, because the Signals library
itself doesn't know the difference between STLport on Windows or on Linux per
se. They generally prefer that Jam-related questions go to
firstname.lastname@example.org but usually answer questions here as well.
