fp-bit.[ch] has the interesting issue of FLOAT_BIT_ORDER_MISMATCH and 
FLOAT_WORD_ORDER_MISMATCH being defined by makefile rules when it ought to 
be possible to deduce that information from macros predefined by the 
compiler.  (See what I said in 
<http://gcc.gnu.org/ml/gcc-patches/2010-11/msg02262.html> about the 
meanings of those macros.)

dfp-bit.* and fixed-bit.* can probably move along with fp-bit.* (or 
before, or after), and I don't think there are any complicated issues 
around those files.
