Subject: Do not use Carp, fix propagation of replace/skip
X-Git-Tag: accepted/trunk/20130322.191538~3330^2~36
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a64e87a87d0e2ae60377d3ed2647be0b75ffea3a;p=platform%2Fupstream%2Fperl.git

Do not use Carp, fix propagation of replace/skip

Using Carp in a module this early in the toolchain can cause ugly
failure. Carp can trigger loading overload. overload::StrVal can trigger
loading Scalar::Util. Scalar::Util::PP requires B. miniperl doesn't like
loading shared libraries.

This problem with Carp just shadowed the underlying problem that the
replace/skip options weren't propagated correctly.
