Subject: Fix a "set but not used" warning on newer gccs.
X-Git-Tag: 1.8.20.0-rc1~41
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9ea3e78e545eaed4f033365ff108452860d23f81;p=thirdparty%2Fasterisk.git

Fix a "set but not used" warning on newer gccs.

Turns out the "helpful" setting of ms and res in this
macro is completely useless after the timeout antipattern
fix.

If you're a new guy looking to write code, don't write
a macro like this one.
