Latest release missing includes? Or reverted good changes?

[Caleb Maclennan]

I'm having trouble building the latest 3.17.0 release for official Arch Linux packages:

In file included from src/cancel.h:8,
                 from src/cancel.c:40:

Reviewing the code changes, I ran across this old CHANGES entry:

* Get rid of uintptr_t to remove dependency on stdint.h

It looks like this is something that got fixed at some point and is now unfixed. Or is there supposed to be some new build time dependency?

I love optional stuff in standard headers :-).

Just fixed and moved the release/tag there (didn't feel like creating a new tag and release for what amounts to a compilation fix).
