bug#16001: [5ef95e85] fails to build with --enable-gcc-warnings in some configurations

["Jan Djärv" <jan.h.d@swipnet.se>]

Hello.

There are lot of new errors in window.c, xterm.c and xdisp.c after the pixelwise resize checkin, so this report is kind of obsolete.  But I checked in fixes for the issues below.
