Jeff Johnston <jjohnstn@redhhat.com> * libc/include/_ansi.h: Add _LONG_LONG definition. * libc/include/math.h (llrint, llrintf, rintl, lrintl, llrintl): Add prototypes. * libc/machine/i386/machine/fastmath.h: Add support for new i386 fast math versions of rint, lrint, and llrint family functions. * libm/machine/i386/Makefile.am: Add new files. * libm/machine/i386/Makefile.in: Regenerated. * libm/machine/i386/f_llrint.c, libm/machine/i386/f_lrint.c, libm/machine/i386/f_rint.c, libm/machine/i386/f_llrintf.c, libm/machine/i386/f_lrintf.c, libm/machine/i386/f_rintf.c, libm/machine/i386/f_llrintl.c, libm/machine/i386/f_lrintl.c, libm/machine/i386/f_rintl.c: New files with fast math implementations.
