[KOS] Patch needed to build with GCC 5.1.1

[Luke B. <ka...@gm...>]

Hi there!

I wasn't sure where bug reports for Kos are supposed to go, so I figured
just emailing here might be the best thing to do.

I had some trouble compiling Kos on Fedora 22 which ships with GCC 5.1.1.
Turns out that the openwrt project had exactly the same compilation issue
and this is the patch to GCC that fixes it:
https://github.com/981213/openwrt/commit/f1a46cdab03240df27d7632a2adac509d58118e8

After applying that to my local tree, Kos compiled successfully.

Luke.

P.S. Just as a side note, any chance of moving over to GitHub? Normally I'd
just be able to send a pull request for this kind of thing, but sourceforge
doesn't seem to have something similar.
