portability fixes and corrected prototypes for self-contained build

gdk-pixbuf/ChangeLog

+2000-11-11  Hans Breuer <Hans@Breuer.Org>
+
+	* gdk-pixbuf-io.c : Fix all function prototype macros for self 
+	contained image handlers (!USE_G_MODULE). Files to save should
+	be opened in binary mode, fopen(s, "wb").
+
+	* io-xpm.c : added HAVE_UNISTD_H condition
+
 2000-11-11  Tor Lillqvist  <tml@iki.fi>
 
 	* gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
