Subject: tests: question mark is extended regex for non-GNU grep.
X-Git-Tag: v2.4.4~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8083d2b47b56808a65b1a2435f2c9801fcd4d312;p=thirdparty%2Flibtool.git

tests: question mark is extended regex for non-GNU grep.

Accepting \? for at-most-once in basic regex is a GNU grep
extension, not accepted by AIX grep for example.
* tests/libtool.at: Use \{0,1\} instead of ? with GREP.
