Subject: BUILD: task: fix build at -O0 with threads disabled
X-Git-Tag: v2.4-dev12~68
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b7e0c633e89fabf04966f4ac14d5902d96b8c7a6;p=thirdparty%2Fhaproxy.git

BUILD: task: fix build at -O0 with threads disabled

grq_total was incremented when picking tasks from the global run queue,
but this variable was not defined with threads disabled, and the code
was optimized away at -O2. No backport is needed.
