Rene,
in 

   https://zigzag.cs.msu.su:7813/boost.build/ticket/81

you said V2 does not support recursively dependent libs. I believe you've 
added the --start-group/--end-group to gcc command line to address that. Is 
the issue now closed?

Incidentally, we have quite a lot of code to property order libraries on 
command line for Unix. I'm not sure what to do with that code. It was written 
because some folks said --start-group causes performance degradation. 

It would be interesting to know if --start-group causes performance 
degradation even if there are no circular dependencies and libraries on 
command line are property sorted.

If yes, and that performance degradation is serious, we might need to have an 
option 'allow circular dependencies'

If no, then --start-group is way to allow circular dependencies without 
penalizing common case, so we can just close the issue.

Any options?

BTW, why do you have circular dependencies between libraries at all?
