From d4362fe972442cfd2d6aa9b32134240c0ddaa6c5 Mon Sep 17 00:00:00 2001 From: Nicolas Pena Date: Thu, 27 Jul 2017 15:52:36 -0400 Subject: Define SIZEOF_VOIDP and other cleanup in tiffconf MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This CL uses sizeof to calculate sizes in tiffconf. It adds SIZEOF_VOIDP to allow LibTIFF to take codepaths reducing OOMs. Finally, it gets rid of _FX_WIN32_MOBILE_ since it's never defined.
