Implement build rules for includes

[snowleopard]

See #16.

The following files need to be generated:

• includes/ghcautoconf.h Done: 6b7b9cc.
• includes/ghcplatform.h Done: 8c32f2c.
• includes/ghcversion.h Done: 66f18be.
• includes/dist-derivedconstants/header/DerivedConstants.h Done: c6cfb36.
• includes/dist-derivedconstants/header/GHCConstantsHaskellType.hs Done: c6cfb36.
• includes/dist-derivedconstants/header/platformConstants Done: c6cfb36.
• includes/dist-derivedconstants/header/GHCConstantsHaskellWrappers.hs Done: c6cfb36.
• includes/dist-derivedconstants/header/GHCConstantsHaskellExports.hs Done: c6cfb36.

Please add other includes files that need attention to the above list.

As the first step I improved the infrastructure we have for generated files: now generators live in directory Rules/Generators/ and we track changes in them. The relevant commit: 8c3022d.

[snowleopard]

We can now generate includes/ghcautoconf.h: 6b7b9cc.

[angerman]

Going to give this a try shortly.

Now we are missing `includes/ghcplatform.h" :-)

[snowleopard]

@angerman Done :-) See 8c32f2c.

That's probably enough for today. The next one is includes/ghcversion.h. I'll work on it tomorrow unless anyone picks it up earlier.

[angerman]

Ha, I was just going to give this a try. Well done! I’ll see if I can get includes/ghcversion.h then :D

@angerman Thanks! All infrastructure is in place, so this should be fairly straightforward, but a bit tedious.

Another file to generate: includes/dist-derivedconstants/header/GHCConstantsHaskellExports.hs (#53).

Wouldn't that live in compiler/includes/dist-derivedconstants/header/GHCConstantsHaskellExports.hs?

[snowleopard]

@angerman I don't see any includes directory in compiler.

I think we are talking about includes/dist-derivedconstants/header/GHCConstantsHaskellExports.hs.

[snowleopard]

OK, I think I've done all includes apart from includes/ghcversion.h.

@angerman, this is now up to you to finish :-)

[angerman]

Adding pressure. I see. Alright, I'll give it a show now.

[snowleopard]

There may be some other files we missed, but I'm closing this for now.

[snowleopard]

I've done a test build, everything works fine. However, we are not needing includes/ghcversion.h anywhere in the system yet.
