Subject: Get rid of a compiler warning with gcc 4.6.3
X-Git-Tag: collectd-5.3.0~23
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=a38c24034ce1831ebfaa41ca6231bb15e17086a7;hp=094bea135e8932101e889ed9ed0965c9067a1db5;p=collectd.git

Get rid of a compiler warning with gcc 4.6.3

...a futile warning that nevertheless kills the build thanks
to -Werror: "variable 'status' set but not used"
