Just to clarify -- is the problem in the naming? Or in something else?

1. Use

        bjam <other options> -n -a

to veryfy the above flags are indeed passed

2. Use

        bjam <other options> target-os=windows

to use the naming of targets suitable for Windows. It appears that you
have built bjam for cygwin, so it defaults to that operating system.
