Well, I've had to hack gcc.jam to use -Wl,"-(" and -Wl,"-)" in order 
to navigate around cyclic dependencies in my *lots* of legacy code :-((
So this does not matter to me, but people with a better library design 
will of course care ;-)) 
Yes, I see the design decision.
But this won't work for sun.jam, because this has OPTIONS on the front 
of the link action (or the sun linker does some strange things, I don't 
know ...)

This would at least solve my problem but introduce problems with the 
scenario noted above. *sigh*
