 big endian portability
 Migration from upstream 5.8 to 5.9 introduces a failure in build process on
 big endian architectures: powerpc, s390 and sparc, with messages like
 .
 terminal_interface-curses.ads:347:41: size for "Character_Attribute_Set" too small, minimum allowed is 32
 .
 The affected parts representation clauses are generated. The trouble is
 related to the changes of procedure gen_reps() in C source gen/gen.c.
 .
 The goal was to remove the GNAT warnings about unused bits. This patch
 directly suppresses the warnings.
 .
 On Debian, gnat >= 4.4 allows accurate warning selection like
  printf ("pragma Warnings (Off/On, \"* bits of \"\"%s\"\" unused\");", nawe);
 but upstream prefers this solution which is available on older gnat versions
  printf ("pragma Warnings (Off/On);");
