[wxhaskell-devel] Fix building with GHC 7.4.1

[shelarcy <she...@gm...>]

Hi,

GHC 7.4.1 can't build wxHaskell. This problem is caused by Num class change
and TypeSynonymInstances extension's change.

I made patch to fix this problem.

Attached patch also include two more changes. I relaxed time and array package's
dependency to use GHC 7.4.1 bundled version instead of installing from HackageDB.
And I commented out wxcore/Setup.hs' unused ver variable to fix builing with my
environment.
