adjust Bison to recent gnulib changes

[Paul Eggert]

I installed this so that CVS Bison continues to build out of the box.

2007-01-26  Paul Eggert  <address@hidden>

        Adjust to recent gnulib changes.
        * src/system.h: Don't include <stpcpy.h>; this is now done by
        <string.h>.
        * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
        Add string.h, string_.h, unistd_.h, wchar_.h.
        * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
