current_Exception can be found in

nm /usr/x86_64-w64-mingw32/sys-root/mingw/lib/libucrtbase.a | grep __current_e 0000000000000000 T __current_exception_context 0000000000000000 I __imp___current_exception_context 0000000000000000 T __current_exception 0000000000000000 I __imp___current_exception

and a few other libraries there.

Apparently with target-os=windows the additional properties binary-format=pe abi=ms have to be specified.

It's not clear why the stacktrace does not build. Sounds like some missing library but it's not clear if gcc missed adding it or boost build system missed it. In any case changing the stacktrace with boost.stacktrace.basic=on boost.stacktrace.from_exception=off something gets built.
