There was some evidence, however, that when the href attribute used a slightly different URL (just a fragment identifier, for instance) then the anchor text was counted.
FWIW: I did somewhat of a test on this a while back (probably around the time Tedster mentioned).
What I did was alter some existing links by adding a fragment identifier to one secondary link on each of about 100 pages, all pointing to the same page.
For me that made no difference, no benefit ever turned up.
Makes me think that IF this works, it may need to be applied when the secondary link is first published. I haven't tested that.
