Tor Lillqvist 143002cac5 Remove, as this is a file generated by configure (or copied from 
1999-11-21  Tor Lillqvist  <tml@iki.fi>

* gdk/gdkconfig.h: Remove, as this is a file generated by configure
(or copied from gdkconfig.h.win32 on Win32, sigh).

* gdk/gdkprivate.h: Mark gdk_parent_root for export from DLL.

* gdk/gdkgc.c (gdk_gc_alloc): Remove duplicated line.
