Yes, this is comparing apples and oranges, but allinanchor gives more reliable picture in Google, at least for the domain name in anchors. If you can figure out the aproximate ratio of domain vs. keywords in anchors then you can come very close.

E.g.
allinanchor:example.com/

more esoteric (with less results!):
allinanchor:example.com/*

or external links only:
allinanchor:"example.com/" -site:example.com
