Subject: Avoid compiler complaints if _TIME_BITS defined when building zlib.
X-Git-Tag: 2.1.4~34
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=faf6cf70cd622b66b1599c36d192601f95780fb9;p=thirdparty%2Fzlib-ng.git

Avoid compiler complaints if _TIME_BITS defined when building zlib.

zlib does not use time_t, so _TIME_BITS is irrelevant. However it
may be defined anyway as part of a sledgehammer indiscriminately
applied to all builds.
