(identities): Add epsilon for float in second identity test. * sysdeps/m68k/huge_val.h: Change GCC's HUGE_VAL{,F,L} to use DI and SI mode integers instead of bytes. Fix value of HUGE_VALL. * sysdeps/m68k/nan.h: New file. * sysdeps/m68k/fpu/__math.h (isgreater, isgreaterequal, isless, islessequal, islessgreater, isunordered): Fix assembler syntax. * sysdeps/m68k/fpu/fraiseexcpt.c: Do it right so that gcc doesn't optimize out the operations. * sysdeps/libm-ieee754/s_nan.c: Use NaN macro instead of static constant. * sysdeps/libm-ieee754/s_nanf.c: Likewise. * sysdeps/libm-ieee754/s_nanl.c: Likewise. * math/carg.c [NO_LONG_DOUBLE]: Add alias for long double function. * sysdeps/libm-ieee754/s_erf.c: Likewise. * sysdeps/libm-ieee754/s_fdim.c: Likewise. * sysdeps/libm-ieee754/s_fmax.c: Likewise. * sysdeps/libm-ieee754/s_fmin.c: Likewise. * sysdeps/libm-ieee754/s_log2.c: Likewise. * sysdeps/libm-ieee754/s_nan.c: Likewise. * sysdeps/libm-ieee754/s_remquo.c: Likewise.
