Subject: Try a different way to silence GCC.
X-Git-Tag: collectd-5.6.0~5^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F1899%2Fhead;p=thirdparty%2Fcollectd.git

Try a different way to silence GCC.

On some distro's some versions of GCC warn about the unchecked result,
even though it is casted to void.

See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66425 for the
discussion.
