Mysterious Cygwin GCC 3.4.4 link problems
Does anyone have a clue about this? Other toolsets, including gcc-2.95.3, gcc-3.3.3, and gcc-4.0.0 all work fine.

Been there. That's not the problem. The problem is that BBv2's gcc support leaves out something crucial that's present in v1: adding the GCC installation's library path to the link path explicitly. In other words, the link command needs to be: /usr/local/gcc-3.4.4/bin/g++ -L/usr/local/gcc-3.4.4/lib ...whatever... As it turns out, this started to break sometime after I ran the Cygwin setup program and it replaced my previous default g++ (3.3.3) with a new version 3.4.4. There's a discussion of these issues in http://thread.gmane.org/gmane.comp.lib.boost.build/8887, but I fear it is still unresolved.
