Hi Vladimir,<br>  <br>  Sorry for delay - I seem to have wincvs firewall issues at work so have to do this from home.<br>  <br> Hopefully this will pass scrutiny.&nbsp; I tested with my  fledgling toolset.&nbsp; When I have some slack time I'll take a stab  at creating a formal regression test case unless you beat me to the  punch.<br>  <br> See the "hack" comment in virtual-targets.jam - Can  the unix handling for "lib" prefix be removed and replaced with a call  to the new type.set-generated-target-prefix in the unix toolkit?&nbsp;  (Unix derived toolkits might not like this so I'm not sure about it.)<br>  <br>  Regards,<br>  Mark<br>  <br>
