 It's very similar to the IBM mainframe format.  So, a port
 of FreeBSD to the IBM mainframe could still use it.  (The VAX
 format was just a copy of the IBM one with an extra precision bit 
 thrown in every now-and-then.)

 But - even the mainframe has an available/alternate IEEE format now,
 and the mainframe version of gcc uses that...  (although, our
 C/C++ compiler for mainframe Linux can optionally use the older
 format.)
