Subject: Try a different way to silence GCC.
X-Git-Tag: collectd-5.6.0~5^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=8422e7e438bf34c075af3b1b6380fe8c1fb82bf9;p=collectd.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.
