Joe Kerian <jkerian@us.us.ibm.com>
[BZ #2749]
* sysdeps/ieee754/ldbl-128ibm/s_copysignl.c:
Include <math_ldbl_opt.h>.
Remove weak_alias. Use long_double_symbol macro.
(__copysignl): Use signbit() for comparison.
* sysdeps/ieee754/ldbl-128ibm/s_fabsl.c: Correct parms for
SET_LDOUBLE_WORDS64.
[BZ #2423, #2749]
* sysdeps/ieee754/ldbl-128ibm/s_ceill.c: Don't include <fenv_libc.h>.
(__ceill): Remove calls to fegetround(), fesetround().
* sysdeps/ieee754/ldbl-128ibm/s_floorl.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm/s_roundl.c: Likewise.
* sysdeps/ieee754/ldbl-128ibm/s_truncl.c: Likewise.
