The type long double is part of the C standard.  See ANSI/ISO 9899-1990,
section 6.1.2.5:

	There are three floating types, designated as float, double, and
	long double.  The set of values of the type float is a subset
	of the set of values of the type double; the set of values of
	the type double is a subset of the set of the set of values of
	the type long double.

Admittedly, there are still C compilers in use that don't support long
double -- just as there are still Ada compilers in use that don't support
the new features of Ada 95.
