Remove `#pragma }'.

* gtk/gtkfeatures.h.in: Remove `#pragma }'.

* gdk/gdki18n.h: Update to use new `glib' widechar defines.

* configure.in (CFLAGS): Don't use test -z "echo .. | grep".  Use
case instead.
(wchar.h, wctype.h, iswalnum): Duplicate widechar tests from `glib'.
(GDK_WLIBS): New variable.  Lists extra libraries needed to use
widechar functions.
* gtk-config.in (--libs): List $GDK_WLIBS, too.
