+       (add_exclude, add_exclude_file): Use xnrealloc instead of rolling

+       * fnmatch.c (SIZE_MAX): Define if standard headers don't.
+       (fnmatch): Do not alloca more than 2000 wide characters;
+       instead, use malloc for large buffers.
+       Check for address arithmetic overflow, and return -1
+       with errno set to ENOMEM in that case.
+       * fnmatch_loop.c (ALLOCA_LIMIT): New macro.
+       (NEW_PATTERN): Do not alloca more than 8000 bytes;
+       instead, return -1.  Check for address arithmetic overflow.

        Handle invalid suffixes and overflow independently, so that
