When I put <variant>release in requirements of an exe, I get pretty strange 
behaviour indeed. Only the value of <variant> is changed, but things like 
<optimization> and <debug-symbols> are not changed.

I'd say it's a bug. Alas, I'm not sure when I'll be able to address it 
though.. maybe, you could look at "basic-target.refined-properties" method in 
targets.jam and see if a call to 'expand-composites' method on 
'erequirements' will help? If so, you might be able to send a patch, or I'll 
be able to fix this quickly when I get to work on Boost.Build.
