        * gtk/gtk*.h:
        * gdk/gdk.h: removed all occourances of #pragma } and #pragma {
        which were in place to fixup emacs' cc-mode indentation.
        putting (c-set-offset 'inextern-lang 0) into ~/.emacs is the
        proper way to achive this and doesn't produce problems for
        stupid pragma-related compiler bugs. ;)
