6529 aix31.h, aix3newas.h, aix41.h, aix43.h, beos.h,
6530 with the aim that rs6000.h is the first header
6531 included and the others override it.
6534 * x-aix41-gld: Remove.
6536 * x-aix41: Remove target-specific switches, and don't specify
6537 -Wl,-bbigtoc as we don't need it any more.
6538 * ../../configure.in: Use x-aix41 for ppc AIX 4.1 and above.
6539 Use t-aix43 for AIX 4.3 and above.

6553 (output_toc): Also do duplicate constant elimination
6554 for per-translation-unit TOCs.
6556 * rs6000.md (nonlocal_goto_receiver): Put it back as before. Add
