Oh, forget it.  That's unsupported.  Use cmd, please.

No, it uses the shell, as you can clearly see in the error messages
for failed tests, that are all setting shell variables using
redirection, and chaining with && and ||.

If you use a "windows bjam" (built from the cmd shell) you need to run
it from inside cmd.  If you use a "cygwin bjam" (built from cygwin
bash) you need to run it from inside cygwin bash.  Those are the only
two options on windows, and Boost.Build doesn't support cygwin at all
anymore, so that may cease to work any day now.
