Thanks for the report. Only a subset of the files are probably truly necessary, 
but for consistency I adjusted all the mips files [1]. Try the patch out if you 
can to see if it addresses the issue.
There are a few left in dec_neon, but I don't think they'll trigger this 
warning. I can normalize those in another patch.

This seems to fix it. Builds without errors with this patch on F22 with GCC 
5.1. Thank you.
