GHC 7.6.1 can't build WXWIDGETS_2_8 branch's wxdirect and wxcore. I made change to fix this problem.
I splited my changes into two part, their are general change ( shelarcy@5149eb3 ) and WXWIDGETS_2_8 specific one. So, I think that we can pick general change to fix HEAD's same problem.
I already uploaded fixed version to HackageDB. Becase HackageDB's version didn't reflect c31ca7c change, too. That causes building problem.
Fix building with GHC 7.6.1
This change doesn't have WXWIDGETS_2_8 specific change for helping
to pick (or merge) this change to HEAD.
I'll commit WXWIDGETS_2_8 specific change next time.
