That's exactly the kind of scenario for which I have written
C->Haskell:
http://www.cse.unsw.edu.au/~chak/haskell/c2hs
Using C->Haskell, you write into the binding module
{#enum bar as Bar#}
run it through the tool and get a Haskell data definition
for `Bar', so that you can safely marshal between C's bar
and Haskell's Bar. (See also the corresponding section in
the manual
<http://www.cse.unsw.edu.au/~chak/haskell/c2hs/docu/c2hs-3.html#ss3.5>.)
