- Subject: [PATCH] configure: recognize modern GNU sed
Starting with commit 4.2.1-20-ga9bf076, GNU sed is using version-etc-fsf
module from gnulib, so its --version output style changed from
"GNU sed version 4.2.1" to "sed (GNU sed) 4.2.1".
2012-08-22 Dmitry V. Levin <ldv@altlinux.org>
* configure.in (SED): Update AC_CHECK_PROG_VER's version extract regexp
to support sed >= 4.2.1-20-ga9bf076.
* configure: Regenerated.
