   8 GCC 8.1 added some new warnings, including warning about parentheses
   9 with no effect in variable declarations.  GTK2 headers have a few of
  10 these, which produce a lot of warnings in projects using GTK2.
  11
  12 The warnings look like:
  13 /usr/include/gtk-2.0/gtk/gtkfilechooserbutton.h:59:8: warning:
  14 unnecessary parentheses in declaration of ‘__gtk_reserved1’ [-Wparentheses]
  15    void (*__gtk_reserved1);
  16         ^
  17
  18 Removing the parentheses is harmless and fixes the warnings.
