One way is to do something like this for the headerfiles:
AC_CONFIG_FILES([include/Motif-1.2/Xm/Xm.h.tmp:include/Motif-1.2/Xm/Xm.h.in],
[if cmp -s include/Motif-1.2/Xm/Xm.h.tmp
include/Motif-1.2/Xm/Xm.h 2>/dev/null
then
AC_MSG_NOTICE([include/Motif-1.2/Xm/Xm.h is unchanged])
AC_MSG_NOTICE([deleting include/Motif-1.2/Xm/Xm.h.tmp])
rm -f include/Motif-1.2/Xm/Xm.h.tmp
else
AC_MSG_NOTICE([updating include/Motif-1.2/Xm/Xm.h])
rm -f include/Motif-1.2/Xm/Xm.h
mv include/Motif-1.2/Xm/Xm.h.tmp
include/Motif-1.2/Xm/Xm.h
fi])
