Understood, but IIUC --build-type=complete doesn't generate static
libraries that link to the dynamic runtime.  Humm...

Reviewing what the BoostPro installer puts on the disk (carefully,
this time!) I see

threading=multi   debug   link=shared runtime-link=shared
threading=multi   release link=shared runtime-link=shared
threading=multi   release link=static runtime-link=shared
threading=multi   debug   link=static runtime-link=shared
threading=multi   release link=static runtime-link=static
threading=multi   debug   link=static runtime-link=static
threading=single  release link=static runtime-link=static
threading=single  debug   link=static runtime-link=static

which looks like the following build request to me:

  debug release

However, that doesn't seem to be what the code in Jamroot is doing.
