Is it OK that I only edit the message to include "If you are deriving Typeable for a polykinded datatype, make sure PolyKinds is on"?

#3333: GHCi doesn't load weak symbols ---------------------------------+----------------------------------------- Reporter: heatsink | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.6.2 Component: GHCi | Version: 6.10.4 Resolution: | Keywords: weak, dynamic loading Operating System: Linux | Architecture: x86 Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: 3658 Blocking: | Related Tickets: ---------------------------------+----------------------------------------- Comment (by akio): Replying to [comment:32 ezyang]: > igloo: If the patch is already implemented and does not cause any trouble for anybody, I think we should take it. It is not that complicated either. Indeed it would be nice if this can be fixed in the GHCi linker, too. I rebased the patches. They validate on Linux. I also tried to validate on Windows but haven't managed to do it, due to some other issues (probably I haven't set up my environment correctly). (I accidentally attached an unrelated patch {{{0001-Test-for- Trac-8242.patch}}}, but I don't know how I can delete it.
