re PR tree-optimization/85699 (gcc.dg/nextafter-2.c fail)
PR tree-optimization/85699
* gcc.dg/nextafter-1.c (NO_LONG_DOUBLE): Define if not defined. Use
!NO_LONG_DOUBLE instead of __LDBL_MANT_DIG__ != 106.
* gcc.dg/nextafter-2.c: Include stdlib.h. For glibc < 2.24 define
NO_LONG_DOUBLE to 1 before including nextafter-1.c.
