+From a3beacc11e2acbe0baf8b301cb47938dcf01e71d Mon Sep 17 00:00:00 2001
+From: Sam James <sam@gentoo.org>

+Subject: [PATCH] configure.ac: fix bashisms
+
+configure scripts need to be runnable with a POSIX-compliant /bin/sh.
+
+On many (but not all!) systems, /bin/sh is provided by Bash, so errors
+like this aren't spotted. Notably Debian defaults to /bin/sh provided
+by dash which doesn't tolerate such bashisms as '=='.
+
+This retains compatibility with bash.
+
+Fixes configure warnings/errors like:
+```
+checking for cheev_ in -llapack... yes
+./configure: 8590: test: x: unexpected operator
+checking how to print strings... printf
+```
