That would risk breaking little endian platforms that failed to define
this. Safest to limit the scope of the change the PPC platforms, where
__LITTLE_ENDIAN__ is a new option, and hence likely to be set correctly.
I would sure like to be able to detect the difference between 'this
option is set to false' and 'this option isn't defined'; is there
something that PPC defines in both cases, and sets to TRUE in one case
and FALSE in the other?
I'm probably missing something (maybe this header cannot include a
dix-config.h or equivalent), but why not use AC_C_BIGENDIAN?
Because tradition! And because Imake didn't work that way!
But mostly because no one has had the patience to change it since,
and to make a servermd.h.in that configure can generate servermd.h
from to install for use by driver builds that may not have the exact
same macros set by AC_C_BIGENDIAN in their builds.
