26 * Revision 1.7 1999/09/17 02:44:19 tjump
27 * I changed the xxxGetProcAddressEXT function declarations to be more
28 * MSVC friendly. Brianp - could you verify that they describe and operate
29 * as intended on Linux/ETC platforms?
31 * Revision 1.6 1999/09/16 16:54:22 brianp
32 * GLU_EXT_get_proc_address clean-up
34 * Revision 1.5 1999/09/14 03:23:08 gareth
35 * Fixed GLUtriangulatorObj again (spelling).
37 * Revision 1.4 1999/09/14 01:32:58 gareth
38 * Fixed definition of GLUtriangluatorObj for 1.3 tessellator.
40 * Revision 1.3 1999/09/11 11:34:21 brianp
41 * added GLU_EXT_get_proc_address
43 * Revision 1.2 1999/09/10 02:08:18 gareth
44 * Added GLU 1.3 tessellation (except winding rule code).
46 * Revision 1.1.1.1 1999/08/19 00:55:40 jtg
49 * Revision 3.6 1999/02/14 03:39:45 brianp
52 * Revision 3.5 1999/01/03 03:02:55 brianp
53 * now using GLAPI and GLAPIENTRY keywords, misc Windows changes (Ted Jump)
55 * Revision 3.4 1998/12/01 02:34:27 brianp
56 * applied Mark Kilgard's patches from November 30, 1998
58 * Revision 3.3 1998/11/17 01:14:02 brianp
59 * minor changes for OpenStep compilation (pete@ohm.york.ac.uk)
61 * Revision 3.2 1998/07/26 01:36:27 brianp
62 * changes for Windows compilation per Ted Jump
64 * Revision 3.1 1998/06/23 00:33:08 brianp
65 * added some WIN32 APIENTRY, CALLBACK stuff (Eric Lassauge)
