# ieee		- for most IEEE machines, we hope.
# mc68881	- the, ahem, mc68881.
# national	- for those ieee machines whose floating point implementation
#		  has similar byte ordering as the NATIONAL 32016 with 32081.
# i386		- i387 NPX, currently the same as "national"
# mips		- for MIPS achitecture machines
# tahoe		- for the tahoe double format.
# vax		- for the vax D_floating format
