Original patch from: gentoo/src/patchsets/glibc/2.9/1073_all_glibc-ldbl-nexttowardf.patch
-= BEGIN original header =-
ripped from Debian
this change was made to generic __nexttowardf, but not the long double version
2008-05-05 Aurelien Jarno <aurelien@aurel32.net>
* sysdeps/ieee754/ldbl-128/s_nexttowardf.c: Include float.h.
(__nexttowardf): Use math_opt_barrier and
math_force_eval macros. If FLT_EVAL_METHOD is not 0, force
x to float using asm.
-= END original header =-
