+
+	* misc.c (end_of_token): Make argument const.
+	* make.h: Update prototype.
+
+	* function.c (abspath, func_realpath, func_abspath): Use
+	PATH_VAR() and GET_PATH_MAX instead of PATH_MAX.
+	* dir.c (downcase): Use PATH_VAR() instead of PATH_MAX.
+	* read.c (record_files): Ditto.
+	* variable.c (do_variable_definition): Ditto.
+
+	* function.c (func_error): Create a new function $(info ...) that
+	simply prints the message to stdout with no extras.
+	(function_table_init): Add new function to the table.
+	* NEWS: Add $(info ...) reference.
+	* doc/make.texi (Make Control Functions): Document it.
+
+	New feature: if the system supports symbolic links, and the user
+	provides the -L/--check-symlink-time flag, then use the latest
+	mtime between the symlink(s) and the target file.
+
+	* configure.in (MAKE_SYMLINKS): Check for lstat() and
+	readlink().  If both are available, define MAKE_SYMLINKS.
+	* main.c: New variable: check_symlink_flag.
+	(usage): Add a line for -L/--check-symlink-times to the help string.
+	(switches): Add -L/--check-symlink-times command line argument.
+	(main): If MAKE_SYMLINKS is not defined but the user specified -L,
+	print a warning and disable it again.
+	* make.h: Declare check_symlink_flag.
+	* remake.c (name_mtime): If MAKE_SYMLINKS and check_symlink_flag,
+	if the file is a symlink then check each link in the chain and
+	choose the NEWEST mtime we find as the mtime for the file.  The
+	newest mtime might be the file itself!
+	* NEWS: Add information about this new feature.
+	* doc/make.texi (Options Summary): Add -L/--check-symlink-times docs.
+
+	Avoid core dumps described in Savannah bug # 12124:
+
+	* file.c: New variable snapped_deps remember whether we've run
+	snap_deps().
+	(snap_deps): Set it.
+	* filedef.h: Extern it.
+	* read.c (record_files): Check snapped_deps; if it's set then
+	we're trying to eval a new target/prerequisite relationship from
+	within a command script, which we don't support.  Fatal.
