With bzr, each branch is in its own directory, preferably under the
shared repository (i.e., under the same parent as the trunk directory
and your feature branch).  The same command "bzr branch" that you
issued to clone the trunk will work for the branch, except that the
URL is different:

  bzr+ssh://eliz@bzr.savannah.gnu.org/emacs/emacs-23/

MS-DOS uses GCC, so it will work with lib/ignore-value.h.

MS-Windows already works with lib/ignore-value.h (your change in
sysdep.c already used it).  So there's no need to use #ifndef DOS_NT
in this case.
