 * IEEEFLOAT is true if the representation of type "float" is the IEEE
 * standard 32-bit floating point format, with byte order as defined
 * by SWAPBITS (below). IEEEFLOAT is false if some other representation
 * is used (or, heaven forbid, IEEE representation with some inconsistent
 * byte order). This determines the conditions under which conversions
 * are required when manipulating external binary representations.
 *
 * IEEEFLOAT should be true for:
 *	mc680x0 series, i80x86 series, IBM R6000, MIPS Rx000 series,
 *	SPARC
 * IEEEFLOAT should be false for:
 *	VAX
 *
 * For all non-IEEE architectures, the DPS_FORMATNAME macro must agree
 * 	with the floating point format returned by extensions on that
 *	server, if any.
