Summary: binary.test: nonPortable tests...

Initial Comment:
dgp	curious about the "nonPortable" tests in binary.test
[14:51]	dgp	NaN formatting?
[14:54]	kbk	14.12 is crap. That value isn't the
canonical NaN, which will be either 7ff4 (PA-RISC) or
7ff8 (everything else).
[14:55]	kbk	40.1 should be portable but, but the
comment is wrong - it's NaN, not overflow.
[14:55]	dgp	---- Result was:
		1 -NaN(7ffffe0000000)
		---- Result should have been (exact matching):
		1 -NaN
		==== binary-40.1 FAILED
[14:56]	kbk	OK, OK, 40.1 isn't right.  In fact, the NaN
that it returns is the right one.
[14:56]	kbk	40.3 is exactly the same test, which isn't
endianity-dependent.
[14:57]	kbk	Likewise, 40.4 and 40.6 appear to be the
same test, again not endianity dependent, but they're
looking for -NaN(7ffffffffffff) rather than the
canonical NaN.
