There have been no reports of build or test failures, other than the Solaris /bin/sh one for which Paul Eggert wrote the patch listed below.
Some have raised the issue that egrep and fgrep are now shell scripts (they were executables in 2.18), and thus won't work in a system without a bourne shell. We expect to accommodate the usage of those obsolescent wrappers for "grep -E" and "grep -F" on such fringe systems with a 2.20 release that will follow soon after. I expect to release grep-2.19 tomorrow or Thursday, so any testing you can do before then would be most welcome. grep snapshot: http://meyering.net/grep/grep-ss.tar.xz 1.2 MB http://meyering.net/grep/grep-ss.tar.xz.sig http://meyering.net/grep/grep-2.18.146-ebf3.tar.xz Changes in grep since 2.18.143-b298: Jim Meyering (2): maint: NEWS: move "Improvements" to the top maint: NEWS: adjust wording to reflect move Paul Eggert (1): egrep, fgrep: port to Solaris 10 /bin/sh Changes in gnulib since 2.18.143-b298: * gnulib a0712c3...c2e80b7 (3): > update from texinfo > autoupdate > autoupdate
