Thanks for the bug report.  I installed the following patch into CVS
autoconf.

2004-04-20  Paul Eggert  <eggert@xxxxxxxxxxx>

        * tests/c.at (C keywords): Don't assume that GCC supports
        "restrict" and "inline", as sufficiently-old GCC versions do not
        (also, GCC configured to be in pedantic C89 mode does not).
        Problem reported by Sumit Pandya in:
        http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
