gnome-libs portability patch

[fraioli dg-rtp dg com (Marc J. Fraioli)]

Miguel, or whoever has time, access, and the will:  Please find
attached a small patch which helps gnome-libs configure for me.  DG/UX
has scandir() and alphasort(), but no function prototypes for same.
This patch is needed to compile gnome-libs on this platform.

	Thanks,

	Marc
