Hi Steven,

Thank you very much. I didn't see that define in the response.rsp. I worked
around the problem by adding the define to the b2 arguments.

Should I file an issue for this, or is this expected behavior, going
forward? It seems to me that 1 of 2 issues may be occurring:

1. bcp failed to copy the build, correctly, in this instance.
2. There is an issue with the boost-lib target assuming that staging should
include export libs.

I can live with the workaround.

Regards,
Kevin
