+Rather than using the fork function (which doesnt work on nommu
+systems), simply use the daemon() function instead (which does
+work). this should work the same before and after for all systems.

+nommu systems cannot fork() as the hardware cannot support
+it. irattach uses it as a minor optimization, but it isnt
+necessary for correct functioning of the utility. so add a
+NO_FORK define so we nommu peeps can do CFLAGS="... -DNO_FORK=1
+..." and use it in our embedded systems.
