  Disable Lex and Yacc rules whenever possible if AM_MAINTAINER_MODE
  is used and maintainer-mode disabled.
  * automake.in (Automake::struct): Define nodist_specific.
  Set it in languages yacc, yaccxx, lex, and lexxx.
  (register_language): Default nodist_specific to 0.
  (handle_single_transform): Honor nodist_specific.
  * lib/am/yacc.am (am__skipyacc): Define this in maintainer mode.
  (%EXT%%DERIVED-EXT%, %OBJ%): Use $(am__skipyacc) to disable these
  rules when needed.
  * lib/am/lex.am (am__skiplex): Define this in maintainer mode.
  (%EXT%%DERIVED-EXT%, %OBJ%): Use $(am__skiplex) to disable these
  rules when needed.
  * tests/mmodely.test: New file.
  * tests/pr204.test: Augment to check AM_MAINTAINER_MODE and nodist_
  parsers.
  * tests/Makefile.am (TESTS): ADd mmodely.test.
  * doc/automake.texi (Yacc and Lex): Note dependence on maintainer mode.
