Subject: src/collectd{ctl,-nagios}.c: Remove the standards-flags again.
X-Git-Tag: collectd-5.0.0~32
X-Git-Url: https://git.octo.it/?p=collectd.git;a=commitdiff_plain;h=6e0ffb3d9edba6a4b819ace076aea0e9b5fcea51

src/collectd{ctl,-nagios}.c: Remove the standards-flags again.

Solaris and FreeBSD have problems with it for different reasons. The
huge NAN-block from "collectd.h" has been imported again, instead.
