There is a bug in the Sun 3 C compiler such that under -O,
the `__fixunsdfsi' function in gnulib gets done wrong.
Without -O, it compiles to:

	link a6, #0
	movel a6@(8), d0
	movel a6@(12), d1
	jsr Fund
	unlk a6
	rts

With -O, it becomes:

	link a6, #0
	jsr Fund
	unlk a6
	rts

which doesn't work.

The bottom line is that unless you compile gnulib without -O, casting a
double to an unsigned int won't work (it will always come out zero).
