Attached there is an ebuild patch that fixes the problem for v1.7.1.3 (plus a clean up of the ebuild itself).
Hope to be useful.

You haven't argued the problem at all. What is the rationale to begin to support -w?

The same rationale expressed previously for the bug #293324 (where you commented too); You should know the relation between -Wall / -Werror and socat (as reported upstream: http://www.dest-unreach.org/socat/ see note of 2009/05/09) right? the same apply to -w as it inhibits -Wall breaking the source code as I have reported.

p.s.: also -Wno-errors* isn't officially supported by Gentoo, so why is filtered?

I don't see how this is the same as to stop the compiler from emitting any warnings: -w would very likely disable several QA triggers in portage. -Wno-error (especially for a specific warning) could be useful to set globally in some cases, but inhibiting all warnings is insane.

So let me rephrase the question: Why should we support -w?
