But they're also the only patches available right now, and they're clearly related, so let's pull them in as others are doing too. Specifically, it pulls in the following from the 2.4.x branch: * 313c388dbc023bbcb75d1efed800d0cfc992a6cc * 9939a70b750edd9d05270060cc5cf62ca98cfbe5 * 04bb2af4521b56c1699a2c2431c56c05a7102e69 * e0630cd18f76340d302000f2bf6516e99602b844 * 1e6ca5913eceee906038bc04cc7ccfbe2923bdfd * 2abe1ba8a66864aa82cd9836b37e57103b8e1a3b Bug: https://bugs.gentoo.org/940312 Bug: https://bugs.gentoo.org/940311 Bug: https://bugs.gentoo.org/940313 Bug: https://bugs.gentoo.org/940314 Bug: https://bugs.gentoo.org/940315 Bug: https://bugs.gentoo.org/940316 Signed-off-by: Sam James <sam@gentoo.org> net-print/cups/Manifest | 1 + net-print/cups/cups-2.4.10-r1.ebuild | 322 +++++++++++++++++++++++++++++++++++ 2 files changed, 323 insertions(+)

(Also, while here, change the casing to match the upstream configure script.)

The only new feature is adding libcups-3 support which should be harmless. i.e. The delta betewen 2.0.0 and 2.1_beta1 is almost entirely, modulo libcups-3 support, stuff we would want to backport anyway (obvious and trivial bug fixes).
