It still would not work together with \usepackage{figcaps}, though. I
have the impression that the author of figcaps.sty prefers to put
\label inside of \caption like this:
       \caption{Foo bar.\label{fig:foobar}}
If one does this, figure references work without changes to the code. 

Indeed the sources for figcaps contains the following comment:

,----[ figcaps.dtx ]
| % The page(s) of figures are much like those for the tables, except that
| % the |\label| command must be switched off. This is because the labels
| % have already been defined during the list of captions.
`----

If one does not switch of \label, then one would end up with two
different definitions for that particualr label in the aux file.
