Subject: bzero and zlib patch.
X-Git-Tag: HYLAFAX-4_1BETA3~147
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=af553ea4c07dbcf09ab2860cabd61aee432b1b89;p=thirdparty%2FHylaFAX.git

bzero and zlib patch.

Note: the zlib patch does not quite work properly yet when zlib is located
in say /opt/zlib or /usr/local/zlib.  This will have to be fixed at a
future date.
