Patch for macOS build

[andrew867]

I haven't done this before but here is a patch to allow the software to compile on macOS using homebrew GCC and autoconf/automake.

Can you please submit this as a pull request? (Or at least attach it as a patch so I don't have to copy-paste and fix all the character substitutions)

To do that -- create a fork (this creates a copy of this repository but owned by you) - make your changes on your fork - then open your forked repo on the Github website and click "open pull request".

This enables a bunch of review features which make merging a lot simpler :)

OSX build/install instructions would also be appreciated, if you have them.
