Update.
* math/math.h: Unconditionally include bits/mathdef.h. Declare long double functions only if __NO_LONG_DOUBLE_MATH is not defined. * sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X. Define __NO_LONG_DOUBLE_MATH. * sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X. * sysdeps/i386/fpu/bits/mathdef.h: Likewise.
