Subject: Remove bashisms from configure.in
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ba8aff6baa3da6512153da2772e540de82345bde;p=thirdparty%2Fsarg.git

Remove bashisms from configure.in

Tests using == as equality operator are not portable. They are replaced by
a single =.

Thanks to Renato Botelho for reporting this bug.
