MAINLINE PATCH: Make --param Available for gcc (vs. cc1)

[Jeffrey Oldham <oldham at codesourcery dot com>]

Currently Mark Mitchell's "--param <optimization-constant>=<value>"
command-line option is available only for cc1, not gcc.  This patch
makes it available to gcc also.

2001-02-21  Jeffrey Oldham  <oldham@codesourcery.com>

        * gcc.c (cc1_options): Add "-param".
        (DEFAULT_WORD_SWITCH_TAKES_ARG): Likewise.
        (option_map): Likewise.
        * toplev.c (display_help): Add entry for "--param".
        (independent_decode_option): Fix typographical error.

Tested on       i686-pc-linux-gnu
Approved by     Mark Mitchell (mark@codesourcery.com)

Thanks,
Jeffrey D. Oldham
