2005-02-28 Paul D. Smith <psmith@gnu.org>
* doc/make.texi (Text Functions): Update docs to allow the end
ordinal for $(wordlist ...) to be 0.
* function.c (func_wordlist): Fail if the start ordinal for
$(wordlist ...) is <1. Matches documentation.
Resolves Savannah support request #103195.
* remake.c (update_goal_chain): Fix logic for stopping in -q:
previously we were stopping when !-q, exactly the opposite. This
has been wrong since version 1.34, in 1994!
(update_file): If we got an error don't break out to run more
double-colon rules: just return immediately.
Fixes Savannah bug #7144.
2005-02-27 Paul D. Smith <psmith@gnu.org>
* misc.c (end_of_token): Make argument const.

* scripts/options/dash-q: Add a test for Savannah bug # 7144.
* scripts/options/symlinks: New file to test checking of symlink
timestamps. Can't use filename dash-L because it conflicts with
dash-l on case-insensitive filesystems.
