Subject: Fix missing definition UINT16_MAX under GCC 4.7.
X-Git-Tag: rec-4.0.0-alpha2~45^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=refs%2Fpull%2F3473%2Fhead;p=thirdparty%2Fpdns.git

Fix missing definition UINT16_MAX under GCC 4.7.

std::numeric_limits is used elsewhere, so I went with that.
