Subject: Bug #285191 - Add back the RDEPEND.implicit warning to detect the cases
X-Git-Tag: v2.2_rc68~411
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3b9488a32d6f170387b6dfbf1985e87db556f998;p=portage.git

Bug #285191 - Add back the RDEPEND.implicit warning to detect the cases
where DEPEND is set and RDEPEND is unset in the ebuild, since this
triggers implicit RDEPEND=$DEPEND assignment (prior to EAPI 4) and is
forbidden by the QA team.
