 See http://wiki.mandriva.com/en/Overlinking for a discussion of under and
 overlinking.

 In different circumstances, we want both to be able to link to C libs
 statically and dynamically. For the dynamic case we only want to specify
 direct C lib dependencies or we end up overlinking. For the static case we
 must specify all direct and indirect C libs or we will miss libs and get
 missing symbols.

 A sensible solution is to follow [http://people.freedesktop.org/~dbn/pkg-
 config-guide.html pkg-config] and specify "private" C libs separately from
 normal public ones. This would require extensions both to .cabal files and
 package registration files.
