Subject: Define SIZEOF_OFF_T to fix overflow checks.
X-Git-Tag: take1~309
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=50f9c87342c359fab57fd9ff386fbd3b93c2557f;p=thirdparty%2Fsquid.git

Define SIZEOF_OFF_T to fix overflow checks.

Overflow checks were broken because 'SIZEOF_OFF_T <= 4' was always true
because SIZEOF_OFF_T was not defined and, hence, treated as zero.
