Subject: tests: avoid several spurious failures on Solaris
X-Git-Tag: v1.12.2~47
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aa630a928a586fd8dc8a087337c3462d7f4fd1c6;p=thirdparty%2Fautomake.git

tests: avoid several spurious failures on Solaris

* t/ax/is_newest: Rewrite to be Bourne-compatible, for /bin/sh shells like
Solaris' that are not POSIX-conforming.  The script is so small that such
a rewrite is easier than going through the hoops that would be required to
ensure this script is always executed with a POSIX shell.
* t/ax/is: Add a comment stating that this script is to be kept Bourne
compatible as well.
