Subject: pass a NULL pointer in the service argument (the second) if the port number
X-Git-Tag: upstream/7.37.1~10852
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b2be6799f2be7fa103ef61cbe2a053973d008a5d;p=platform%2Fupstream%2Fcurl.git

pass a NULL pointer in the service argument (the second) if the port number
was 0 as it seems at least some AIX versions don't like a "0" string there
