Description Matt 2008-07-26 15:34:37 UTC

the following error is shown:
cc1: warnings being treated as errors
util.c: In function ‘default_failure_notify’:
util.c:934: error: ignoring return value of ‘write’, declared with attribute warn_unused_result
util.c:935: error: ignoring return value of ‘write’, declared with attribute warn_unused_result

the ubuntu guys also seem to hit this error:
http://www.mail-archive.com/ubuntu-bugs@lists.ubuntu.com/msg920376.html

all in-tree versions of squid-3.0* are affected

removing / disabling -D_FORTIFY_SOURCE=2 "fixed" it for me

gcc-version used was: gcc-4.3.1; glibc-2.7
