+	file will be used.
+	Invoke `m4' on m4sugar.m4, muscles.m4, and the skeleton.
+	(prepare): Given that for the time being changesyntax is not
+	usable in M4, rename the muscles using `-' to `_'.

+	* data/: here.
+
+2002-01-29  Paul Eggert  <eggert@twinsun.com>
+
+	* src/bison.simple (YYSIZE_T): Do not define merely because
+	YYSTACK_USE_ALLOCA is nonzero or alloca or _ALLOCA_H are defined.
+	On some platforms, <alloca.h> does not declare YYSTD (size_t).
+
+2002-01-27  Akim Demaille  <akim@epita.fr>
+
+	Fix `%nonassoc and eof'.
+
+	* src/state.c (errs_dup): Aaaah!  The failure was due to bytes
+	which were not properly copied!  Replace
+	memcpy (res->errs, src->errs, src->nerrs);
+	with
+	memcpy (res->errs, src->errs, src->nerrs * sizeof (src->errs[0]));
+	!!!
+	* tests/regression.at (%nonassoc and eof): Adjust to newest
+	Autotest: `.' is not in the PATH.

+	Reported by Evgeny Stambulchik.
+
+2002-01-20  Marc Autret  <marc@gnu.org>
+
+	* src/system.h: Need to	define __attribute__ away for non-GCC
+	compilers as well (i.e.	the vendor C compiler).
+	Suggested by Albert Chin-A-Young.
+
+2002-01-11  Tim Van Holder  <tim.van.holder@pandora.be>
+
+	* lib/hash.h, lib/hash.c: Renamed __P to PARAMS and used the
+	canonical definition.
+	* src/system.h: Use the canonical definition for PARAMS (avoids
+	a conflict with the macro from lib/hash.h).
