GHC 7.6 still distributes by default with an old version of process, which means that requiring the most recent version prevents GHC from properly bootstrapping out of the box. In this patch, we relax the version requirement on process, disabling proper ctl-c handling when the version is not sufficiently new. Perhaps one problem with lowering the bound, is if someone attempts to install Cabal out of the box on GHC 7.6, the dependency solver will prefer the old installed version, so it is very easy to end up with a cabal-install which doesn't have working ctl-c.
