/* Unfortunately, 4.4 and emacs have conflicting uses of BIG_ENDIAN
   and LITTLE_ENDIAN.  Emacs assumes BIG_ENDIAN will be defined for
   big endian machines and not defined for little endian machines.
   endian.h in 4.4 defines both as values with BYTE_ORDER taking on
   the appropriate one.  I see no way to reconcile the two.  Just
   using the values from endian.h will break a little endian machine
   since BIG_ENDIAN is also defined.  Undef'ing the values from
   endian.h (in the m- file) and redefining only one won't work since,
   for example, wait.h requires both be defined and have values.
   At the current time this is not a problem as we can hack around
   it.  Emacs' only use of BIG_ENDIAN is in lisp.h and then only
   if NO_UNION_TYPE is not defined.  By ensuring that NO_UNION_TYPE
   is defined, we avoid the issue.  We also include endian.h now to
   make sure that the m- file doesn't override the correct value (in
   the big endian case).  */
