Bug List
Global G_rename (const char *element, const char *oldname, const char *newname)
This routine does not check to see if the newname name is a valid database file name.
Global GS_setlight_position (int num, float xpos, float ypos, float zpos, int local)
I think lights array doesnt match sgi_light array
