Subject: configure: Mark conftest variable as unused to pass test with -Werror
X-Git-Tag: 5.2.0dr6~24^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3ab6082a0fec9a5df039fe857a6ac3ca08ecd825;p=thirdparty%2Fstrongswan.git

configure: Mark conftest variable as unused to pass test with -Werror

When using -Werror, the warning for the unused variable would let the test fail,
even if in6addr_any is available.
