+Subject: [PATCH] Fix i686 build -Werror=incompatible-pointer-types complaint
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This was caused with jpeg_mem_dest expecting pointer to unsigned long
+and being fed with pointer to size_t, which may amount to different
+data-width types.  There's also a simple overflow check for such
+cases now.
