+
+       * w32.c (sys_pipe): When failing due to file descriptors above
+       MAXDESC, set errno to EMFILE.
+       (_sys_read_ahead): Update cp->status when failing to read serial
+       communications input, so that the status doesn't stay at
+       STATUS_READ_IN_PROGRESS.  (Bug#13546)

+       * keyboard.c (input-decode-map, key-translation-map): Doc fixes.

+
+       Improve AIX port some more (Bug#13650).
+       With this, it should be as good as it was in 23.3, though it's
+       still pretty bad: the dumped emacs does not run.  See Mark Fleishman in
+       http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
+       * unexaix.c (start_of_text): Remove.
+       (_data, _text): Declare as char[], not int, as AIX manual suggests.
+       (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
+       (orig_load_scnptr, orig_data_scnptr):
+       Now off_t, not long, since they are file offsets.
+       (make_hdr): Use _data, not start_of_data ().
+       This is the key part of the fix.
+       (make_hdr, unrelocate_symbols): Use off_t for file offsets.
+       (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
+
+       * pre-crt0.c (data_start): Initialize to 1.
+       This ports to compilers that optimize the external declaration
+       'int x = 0;' as if it were 'int x;' to shrink the executable.

+
+       Improve AIX port (Bug#13650).
+       This doesn't fix the bug, but it makes progress: Emacs builds now.
+       * unexaix.c: Include inttypes.h, stdarg.h.
+       (report_error, report_error_1): Mark as _Noreturn.
+       (report_error): Don't report the wrong errno.
+       (report_error_1): Now varargs.  All callers changed.
+       (make_hdr): Use uintptr_t, not unsigned, when converting pointers
+       to unsigned.  Don't use ADDR_CORRECT, as it no longer exists.
+       (write_ptr): Use %p to print address rather than %lx and a cast
+       to unsigned long.  Grow buffer a bit, to be safer.
