Hi.

As discussed on IRC some time ago, there are configurations that produce -Werror=maybe-uninitialized
and other warnings that break bootstrap. So that, the patch makes -Werror just for default (boostrap-debug)
configuration.

Ready for trunk?
Martin

Hmm, this enables werror on release branches.  I think we also want to
enable Werror for
--without-build-config (or =yes and =no), thus regular bootstrap
without bootstrap-debug.

Hi.

One has to set stage2_werror_flags in action-if-{not,}-given
in order to properly respect the configure option.

Ready to be installed?
