+        * unexelf.c: Fix some 32-bit integer problems, notably when debugging.
+        Include <limits.h>, <stdbool.h>, <intprops.h>, <verify.h>.
+        Verify that ElfW (Half) fits in int.
+        (fatal): Use same signature as lisp.h.
+        (UNEXELF_DEBUG): New macro, replacing DEBUG, so that people can
+        configure and build with -DUNEXELF_DEBUG without worrying about
+        other modules that use DEBUG.
+        (DEBUG_LOG) [UNEXELF_DEBUG]: New macro.  All debug code that prints
+        possibly-wide integers now uses it instead of plain fprintf.
+        (entry_address): New function, which avoids problems with 32-bit
+        overflow on 64-bit hosts.
+        (OLD_SECTION_H, NEW_SECTION_H, NEW_PROGRAM_H): Use it.
+        (round_up): Don't assume the remainder fits in int.
+        (find_section): Use bool for boolean.  Simplify debug code.
+        (unexec): Don't assume file sizes fit in int or size_t.
+        Omit unnecessary trailing newline in 'fatal' format.
+        Use strerror rather than outputting decimal error number.
+        Remove unused code when emacs is not defined;
+        this file relies on Emacs now.
+        Don't assume e_phnum and e_shnum are positive.
+
         * regex.c: Fix problems when DEBUG is defined.
         (extract_number, extract_number_and_incr): Define regardless of
         whether DEBUG is defined; that's simpler and makes the code less
