Update to 1.9.3:

Bugs fixed in 1.9.3:

* Bug introduced by 1.9:

  - Dependency tracking using mode "dashmstdout" or \ 
"dashXmstdout" did
    not work for libtool objects compiled with --tag (i.e., compiled
    with Libtool 1.5 or later).  The compilation would succeed, but
    `depcomp' would emit a warning and not output any dependency
    information.

* Long standing bugs:

  - Ignore comments from augmented variables, so that
       FOO = foo # bar
       FOO += baz
    no longer results in `FOO = foo # bar baz'.

  - `install-sh -d a/b/' failed to create `a/b/' because of the trailing `/'.

  - _PROGRAMS now always create programs.  Before 1.9 it would
    mistakenly create a libtool library if the name of the program
    ended in `.la'.  Between 1.9 and 1.9.2 a program with such a name
    would fail to build because half the code was assuming a program
    was being built, while the other half was considering a library...

  - `compile' now handles `*.obj' objects.

  - `aclocal' recognizes AC_DEFUN_ONCE.

* Noteworthy manual updates:

  - LIBOBJS: more documentation and an example setup.
  - Libtool Convenience Libraries: show how to force the linker selection.
  - Extending: more comments about install-data-hook vs install-exec-hook.
  - Clean: document -local targets.
