	I've built several perl versions on a Sun 3/160 with 16MB of memory,
	and (I think) around 30-40MB of swap.  I used -O3 on all routines
	except toke.c and eval.c  (also ttoke.c and teval.c too, of course).
	As you note, the optimizer (for Sun cc) gets itself into a tizzy
	and chomps on memory until it runs out of VM (an error from getpage()).
	I dropped to -O2 for those two.  Perl, patchlevels 18, 28(?) and 44
	passed all tests, and has given no problems so far (although now
	that I've said it, things will probably start to fall apart :-)
	Takes a while to build at those optimization levels though, and
	I'm not sure that I gain anything by bumping it up that high. Oh well.
	By the way, perl is a great package; just have to get the book now!
		Cheers!
