Subject: Remove a compiler warning from -O0 build
X-Git-Tag: hostap_2_1~620
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1281c0ab692592a02282e040271ae17a05488062;p=thirdparty%2Fhostap.git

Remove a compiler warning from -O0 build

It looks like abs() result is signed and gcc warns about this when
running a build with -O0 but not with -O2.
