You can change these to whatever you want, and cabal should just start
using those locations, if that helps.

There are others on this list that know cabal much better than I, but
I have been working with it a bit recently, so I'll take a stab..
I don't believe you can configure *cabal* to look on H: for the cabal
config, without specifying . I believe it uses the windows
Application Data directory for your current user to locate the cabal
config (there is a windows system (?) call that returns something akin
to c:\Documents and Settings\username\Application Data\ ). You *can*
change the location of your Application Data directory by hacking the
windows registry, but that is likely to cause more pain than it is
I think you will be best served by just editing the entries in your
cabal config (if that, even) unless you have a very good reason to
relocate the cabal config itself.
(Ok, so I think I lied a little -- iirc, there is an undocumented
cabal flag that will let you specify the path to the cabal config file
to use. I think it has to be the first parameter to cabal, and I
think it's --cabal-config=<file>, but I've only used it once and I
don't think it's really worth the trouble in your case. Application
Data is a pretty standard place for things like this.)
