Dear Isaac,

for the next release, I think *every* external program used by Cabal 
should get a xyz-options (free form) tag to give additional options. We 
already have them for linker, c-compiler, and hs-compiler, but not yet 
for preprocessors and doc generators (haddock). This is very easy to 
implement, does no harm at all, and greatly increases cabal's 
flexibility as a build tool. (BTW, I can send you a darcs patch if you 
are too busy at the moment.)
