  New Revision: 13878

  Modified files:
    trunk/ChangeLog
    trunk/Makefile.in

  Log:
    * Makefile.in (lex.c): touch lex.c if gperf failed.
      Although this may cause non-updated lex.c,
      svn co may generate keywords newer than lex.c especially on
      a file system which can record fractional mtime such as XFS.
