Update to 1.9.6:

Bugs fixed in 1.9.6:

* Longstanding bugs:

  - Correctly diagnose `#' comments following trailing backslash.

  - Preserve backslashes preceding `##' lines.

  - Preserve the order of items conditionally appended (+=) to variables.

  - Fix support of installation directory names with spaces on systems
    where mkinstalldirs cannot use `mkdir -p'.

  - Avoid infinite loop in mdate-sh when TIME_STYLE is set.

  - Do not output two definitions of SOURCES (an internal variable).
    One was not formatted and could exceed the maximum line length of
    some third-party tools (e.g., AIX 5.1 grep, breaking dependency
    tracking).

  - Do not empty info files when attempting to rebuild them without makeinfo.

  - Be smarter when a Makefile.am references files in both "./dir" and
    "dir": do not output two rules to create these directories.
    (PR/461)

  - Do not attempt to recover a missing *.elc file if it cannot be
    created because emacs does not exist.

  - Several aclocal fixes for issues occuring when configure.ac
    includes some other m4 files explicitely with m4_include or m4_sinclude.
    (PR/450)

  - depcomp's cpp mode now understands preprocessors that output either
    `#line 42 file' or `# 42 file'.  (Only the latter was supported.)

* Other miscellaneous changes:

  - Update the GPL, and the FSF postal address.

  - Anticipate for python2.5 in AM_PATH_PYTHON.

  - The manual should now compile without any warning from TeX.
