[PATCH 0/4] Clean-up warnings spotted by Rtags

[marxin <mliska@suse.cz>]

Hello.

For quite some time I've been using Rtags for code completion and other
related stuff. Recently I noticed they provide diagnostics for an entire project.
Doing so, one can get quite some extra warning reported by Clang and I consider some
of them useful.

So that I would like to install my Python script that filters the warnings and few
patches that address the relevant warnings seen.

Patch survives bootstrap and regression tests on ppc64le-linux-gnu machine.
