Build error on Ubuntu 14.04 32-bit

Although this is a duplicate of issue 300, since this occurs every time I've pulled from official repos since 2013, I thought I'd bring it up again here.

The aforementioned issue 300 indicates the patch below. I've tested this on both 64 and 32-bit Ubuntu 14.04 releases as working:
