Subject: Compiler support: fix cc compiler complaints about function results
X-Git-Tag: SQUID_3_0_STABLE8~13
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0cbef577d4266a55ebff705138e02d165734bb42;p=thirdparty%2Fsquid.git

Compiler support: fix cc compiler complaints about function results

Fixes warnings produced by cc compiler about unused function
results. gcc ignores these.

This patch is to fix package generation on Ubuntu. By the looks
of it SuSE linux, Fedora Core, and RedHat also benefit.
