Subject: [ng] tests: fix unportable $((...)) usage
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ce110a94aabb52b6756f4ff29c00414b56697f6;p=thirdparty%2Fautomake.git

[ng] tests: fix unportable $((...)) usage

* t/longline.sh: Use "$i", not bare "i", to reference the value of
the shell variable 'i' in a $((...)) expression.  Issue revealed by
a failure with dash 0.5.2.
