Apparently, I'd have to decide it's not 100% reasonable ;-)

Probably. The interface which returns vector<> is nicer, and we should not
kill a good interface because of a specific compiler. Besides, in this
case, both vector<> returning function and an iterator interface are
reasonable, so if you're on VC7.1 and care about globbing performance, you
can use the iterators interface.
