5590 aix31.h, aix3newas.h, aix41.h, aix43.h, beos.h,
5591 with the aim that rs6000.h is the first header
5592 included and the others override it.
5595 * x-aix41-gld: Remove.
5597 * x-aix41: Remove target-specific switches, and don't specify
5598 -Wl,-bbigtoc as we don't need it any more.
5599 * ../../configure.in: Use x-aix41 for ppc AIX 4.1 and above.
5600 Use t-aix43 for AIX 4.3 and above.
5601 * ../../configure: Regenerated.

5613 one per translation unit, not one per function.
5614 (output_toc): Also do duplicate constant elimination
5615 for per-translation-unit TOCs.
5617 * rs6000.md (nonlocal_goto_receiver): Put it back as before. Add

5634 where they clearly shouldn't be. This may need to be fixed
5635 later when there is a GNU ar for AIX.
5636 * x-aix43: Don't define CLIB or AR_FOR_TARGET.
5637 Don't define BOOT_LDFLAGS as it is now not necessary.

5641 * rs6000.c (rs6000_build_va_list): Use 'char *' rather than 'void *'
5642 for va_list on AIX. Use unsigned_char_type_node rather than
5643 constructing our own version on svr4.
