GNU grep 3.8 warns about some regular expressions that POSIX says have undefined effect, e.g., '\-'. Unfortunately Libtool uses regular expressions of this form. Some unittests now fail, e.g. link-order.at: --- /dev/null +++ .../libtool/tests/testsuite.dir/at-groups/66/stderr @@ -0,0 +1,4 @@ +/bin/grep: warning: stray \ before / +/bin/grep: warning: stray \ before / +/bin/grep: warning: stray \ before / +/bin/grep: warning: stray \ before / Url: https://savannah.gnu.org/patch/index.php?10282 * m4/libtool.m4 (_LT_LANG_CXX_CONFIG): Do not use \- in a BRE or ERE, as this produces undefined results that GNU grep 3.8 warns about. Use [-] instead. * tests/link-order.at (Link order test): Similarly, do not use \/ in an ERE; use / instead.
