As of 11/10/2005 SLgtk has been built at least once, and at least partially
tested, on the following platforms:


	Operating System		Compiler(s)
	----------------		----------------------------

	Solaris 2.6			Sun Workshop: cc v4.2

	Solaris 2.8			Sun WorkShop 6.1: cc v5.2 (w/ Gtk 2.0.x)
					GCC 2.95.2		  (w/ Gtk 2.2.0)
					Sun WorkShop 6.2: cc v5.3 (w/ Gtk 2.2.0)
   						

	Linux, Redhat 7.2		gcc 2.96

	Linux, Red Hat 8.0 3.2-7	gcc 3.2 20020903

	Linux, Debian Woody 		2.4.20-pre10 (prerelease)) SMP
					gcc 2.95.4

	Linux, Debian Sarge		2.6.12.5
					gcc 3.3.5

	Linux, Fedora Core 3		2.6.9-1.667	(AMD Opteron 64 bit)
					gcc 3.4.2

	Compaq Tru64 Unix, V4.0f	gcc 2.95.2
	(formerly Dec/Alpha)

	Compaq Tru64 Unix, V5.1		gcc 3.2.1

	Mac OS/X 10.2 (X11 mode)	Apple GCC, v1151 (based on gcc v3.1
	Darwin Kernel 6.3, 12/14/2002	prerelease)

	Mac OS/X 10.3.1			(against Gtk 2.0.6 and Gtk 2.2.1)

SLgtk proper has been verified to compile and operate against Gtk versions
2.0 through 2.8.6.  However, if you also wish to build the FITS pixbuf
loader (contrib/gdk-pixbuf/io-fits.c) you must use Gtk 2.2 or later.
