* Makefile.cfg (local-checks-to-skip): Add changelog-check,

since we don't want to insist on a version number at the start
of the changelog every time.
* Makefile.maint: Sync from coreutils a bit better.
(sc_trailing_blank): Renamed from sc_trailing_space.
All uses changed.
(sc_no_if_have_config_h, sc_require_config_h):
(sc_prohibit_assert_without_use): New rules.
(sc_obsolete_symbols): Don't catch Makefile.maint itself.
(sc_dd_max_sym_length): Fix leading spaces in rule.
(sc_system_h_headers): Prefix with @.
(sc_useless_cpp_parens, m4-check): Output line numbers.
(changelog-check): Allow version only in head.
* data/c.m4: Use "defined FOO" instead of "defined (FOO)", to
satisfy new Makefile.maint rule.
* data/glr.c: Likewise.
* data/glr.cc: Likewise.
* data/lalr1.cc: Likewise.
* data/yacc.c: Likewise.
* lib/ebitsetv.c: Likewise.
* lib/lbitset.c: Likewise.
* lib/subpipe.c: Likewise.
* lib/timevar.c: Likewise.
* src/system.h: Likewise.
* data/yacc.c (YYSTYPE): Don't generate trailing spaces in output.
* djgpp/Makefile.maint: Add copyright notice.
* djgpp/README.in: Likewise.
* djgpp/config.bat: Likewise.
* djgpp/config.site: Likewise.
* djgpp/config_h.sed: Likewise.

* djgpp/subpipe.h: Likewise.
* lib/bitsetv-print.c: Likewise.
* lib/bitsetv.c: Likewise.
* lib/subpipe.h: Likewise.
* lib/timevar.c: Likewise.
