compile a la bsd
if define SYS5, then problems as macosx lacks some old sysv routines/variables

usual slew of warnings, tied to old code with current ansi compiler

same results with this version on macosx as sysv version on octane
[small differences not worth tracking down, in view of sysv!=bsd branches:

compiled straight under octane irix 6.4

rise_set compiles straight under bsd, on cs dept vax

changes in time functions needed for sys5:
#defined with tests on SYS5, to remove:
	remove sys/timeb.h, struct timeb, ftime() (all bsd specific)
	remove hack to compute XDT vs XST
	replace with set of localdst based on timezone and daylight externals

seems to work, by cf with vax

changed longitude and latitude to tucson values, approximate, 
determined by inspection of county map;
probably ok within 5 minutes of arc = 5/60/360 = .0004

put executable into /usr/games/sunrise


the exact coord of the UofA satellite dish, for computer communications,
came over the net:
