Well, I should say I'm not absolutely opposed to using "#if __BEOS__",
eg, in difficult cases; it just shouldn't be the first resort.

This seems to be a tricky case and I think just putting 
a check for __BEOS__ in dont_run_as_root() would be ok
(where the current __EMX__ check is).

Hmm, maybe resort to #if __BEOS__ here too :-/  
Or as you suggested below.

Should probably check for snooze() in configure and
check HAVE_SNOOZE in myusleep() if not HAVE_USLEEP.
