The only way to implement nextafter that I know of requires to know
the exact representation of the floating point number, and long double
is unfortunately platform dependent.

What is the long double format on solaris sparc ? (big endian I
suppose, but how many bits for the mantissa and  exponent ? Does it
follow IEER754 ?)
