Subject: Silence Clang warning about numeric_limits<> specialization.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/1969499c6fadcac1b8d39e90dce428726f430307?ds=inline

Silence Clang warning about numeric_limits<> specialization.

libstdc++ (which is used by Clang) defines numeric_limits<> as a struct
and Clang issues a warning about our specialization that uses 'class'.
As libstdc++ developers have no intention of fixing this, silence the
Clang warning by using 'struct' for it.
