Re: [patch] list of input files if max_cmd_len exceeded

        Okay, sorry that I missed that.  I can move my change to that
block, but the GNU ld linker script syntax is just different enough that I
cannot reuse the file.  GNU ld wants a file containing 

INPUT (
"filename1"
"filename2"
)

without requiring a commandline option while AIX, at least, wants a file
that simply contains filenames (no quotes) and the file is specified with
a commandline option.

        Also, libtool currently does not delete the temporary linker
script, which it probably should.

Thanks, David


        * config/ltmain.m4sh (func_mode_link): If command exceeds
        max_cmd_len and file_list_spec exists, write list of input files
        to temporary file.
        * m4/libtool.m4 (_LT_LINKER_SHLIBS, aix[45]): Define file_list_spec.
        (_LT_LANG_CXX_CONFIG, aix[45]): Define file_list_spec.
