Thanks for sending this patch!
Unfortunately, I don't think it's correct. The problem is that if I define my
own graph type, then functions like "vertices" are not likely to be defined
in namespace boost. Therefore, if your patch is applied, user-defined graph
types are no longer usable with iteration macroses.
Why the change is needed? Are you on a compiler which does not implement
argument-dependent lookup?
(BTW, it's more convenient if you send your patches as unified diff against
the unmodified sources, in MIME attachment, not uuencoded)
Thanks,
Volodya
