Subject: Make feature tests build with -Wall -Werror
X-Git-Tag: 1.9.9-b1~868^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19d35a361b0632a5e6afa0af815bab89b39c8d32;p=thirdparty%2Fzlib-ng.git

Make feature tests build with -Wall -Werror

The feature tests had a number of unused variables.
Make them appear used by doing a void cast.
