Bug #101496 for Test-Harness: [PATCH] reduce compiler warnings and stderr noise

Dear maintainer of a dual-lived CPAN distribution: I'm currently attempting to get bleadperl to be warnings-clean; i.e. where (./Configure && make) 2>errs leaves no lines in 'errs'. Recently bleadperl made the -W options passed to the C compiler more fascist, and in addition we're trying to get blead to compile and run cleanly under clang's -fsanitize=undefined option. Due to that and other reasons, bleadperl's build is currently very noisy. Attached (hopefully) to this ticket is one or more patches that reduce the noise of your distribution when built as part of bleadperl. It would be great if they could make it into a new release of your distribution in time for incorporation into perl-5.22.0. Our timetable is: 2015-01-20 5.21.8 Contentious changes freeze 2015-02-20 5.21.9 User-visible changes freeze 2015-03-20 5.21.10 Full code freeze 2015-05-20 5.22.0 Stable release! so for example if a new release of your distribution included contentious features, then it would need to be merged into blead *prior* to the 20th of Jan. Thanks, Dave M. -- The Enterprise is involved in a bizarre time-warp experience which is in some way unconnected with the Late 20th Century. -- Things That Never Happen in "Star Trek" #14
