Can't build on 32-bit armv7

Using the latest rustc 1.6 nightly I'm getting this:

and so on for a total of 19 times. Would simple casting fix this issue?

[kattrali]

Thanks, @petevine. Yeah, a cast would handle this. I can take a look sometime later.

[kattrali]

I pushed an update for this, can you confirm the fix?

[MagaTailor]

Yes, it's fixed, thx.

The final linking stage fails though - probably because ncurses is too old? (5.9)

undefined reference to symbol 'halfdelay'

[kattrali]

Hmm, I'm not sure. I thought halfdelay was older than that. Investigating.

[MagaTailor]

I've been wondering about the version of the rust ncurses crate - is 5.73.0 related in any way to the supported version of the underlying library?

[kattrali]

is 5.73.0 related in any way to the supported version of the underlying library?

It doesn't seem to be related, based on how the version numbers are being changed.

Though its also odd that it started at 5.71.0.

[MagaTailor]

I'd been half-expecting this type of failure after originally seeing ncurses 6 mentioned in the readme but still wanted to test the rust parts on arm.
