+       Give more-useful info on a fatal error (Bug#12328).
+       * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
+       (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
+       of doing the work ourselves.
+       * emacs.c (fatal_error_signal): Let fatal_error_backtrace
+       do most of the work.
+       (fatal_error_backtrace): New function, taken from the guts
+       of the old fatal_error_signal, but with a new option to output
+       a backtrace.
+       (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
+       info about the signal than just its number.
+       * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
+       * sysdep.c: Include <execinfo.h>
+       (emacs_backtrace): New function, taken partly from the previous
+       code of the 'die' function.
+       (emacs_abort): Call fatal_error_backtrace rather than abort.
