+       backupfile: remove unnecessary use of m4/dos.m4
+       * m4/backupfile.m4 (gl_BACKUPFILE): Don't require gl_AC_DOS; none
+       of its symbols are used by the backupfile code.  backupfile.c does
+       use a symbol HAVE_DOS_FILE_NAMES, but that symbol is meant only
+       for the rare case of programs that want all their backup file
+       names to live within 8+3 limits, and dos.m4 doesn't address that.
+       * modules/backupfile (Files): Remove m4/dos.m4.

-       Reported by Ralf Wildenhues, with the short needle and haystack.
+       The original problem was reported by Mike Stump in

+       Ralf Wildenhues provided the short needle and haystack.
        * tests/test-strstr.c: Add Ralf's test case to trigger the bug.
        Add a more involved test to trigger the bug in two_way_long_needle.
