* sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c (nextafterl): Remove
unused ily variable. Fix nextafterl on +-__LDBL_MAX__ and +-Inf.
Remove unreachable code at the end.
2007-06-01 Steven Munroe <sjmunroe@us.ibm.com>
* sysdeps/ieee754/ldbl-128ibm/s_fpclassifyl.c: Correct description of
ldbl-128ibm in comment.
(fpclassifyl): Correct classification of denormals.
* sysdeps/ieee754/ldbl-128ibm/s_nextafterl.c (nextafterl): Correct
return value for MIN denormal. Rewrite using long double math too
correctly handle denormals and canonicalize the results.

* sysdeps/ieee754/ldbl-128ibm/mpn2ldbl.c
(__mpn_construct_long_double): Fix conversion where result ought
to be smaller than __LDBL_MIN__, or the low double should be
denormal. Fix decision where to negate low double - honor round
to even rules.
* stdio-common/tst-sprintf2.c: Include string.h.
(COMPARE_LDBL): Define.
(TEST): Also test whether a string hexadecimal float representation
can be parsed back to the number.
(main): Add a couple of further tests.
