Subject: shrinking windows with gtk 3.20

Yaakov Selkowitz has pointed out that the fix for this bug on the 
emacs-25 branch should have used the function gtk_check_version rather 
than the macro GTK_CHECK_VERSION.  The function checks the version at 
runtime, while the macro checks the version at build time.

The effect of using the macro is that the bug can suddenly show up after 
a gtk update, and a rebuild of emacs with the new gtk is required.  See
