Log message:
    The attached patch enables PostgreSQL CVS to build cleanly under Cygwin
    when built against readline 4.2.  Specifically, it handles the deprecation
    of

    filename_completion_function()

    with preference for

    rl_filename_completion_function()

    Although, I was motivated by Cygwin support, IMO this patch is appropriate
    for all platforms.  To quote from the readline source:

    #if 0
    /* Backwards compatibility (compat.c).  These will go away sometime. */
    ...
    extern READLINE_EXPORT(char, *filename_completion_function) ...
    #endif

    Note that this patch is modeled after the one by Peter Eisentraut for
    completion_matches():

    I tested this patch under the following environments:

    Cygwin with readline 4.1
    Cygwin with readline 4.2
    Linux with readline 2.2.1
    Linux with readline 4.2

    and it behaved as expected.
