   Headers such as tm-m88k.h contain macros that refer to functions such as 
   store_floating().  I moved those functions to doublest.h.

I see, but how about the i386/xm-*.h files?  I'm asking since I'm
thinking about replacing most of them with a single xm-i386.h with the
following contents:

   /* FIXME: kettenis/2001-07-29: Get rid of HOST_BYTE_ORDER when Andrew
      has erradicated it from the sources.  */
   #define HOST_BYTE_ORDER LITTLE_ENDIAN

   #define HOST_FLOAT_FORMAT &floatformat_ieee_single_little
   #define HOST_DOUBLE_FORMAT &floatformat_ieee_double_little
   #define HOST_LONG_DOUBLE_FORMAT &floatformat_i387_ext

   Yes, ulgh :-)
