Bison problem with using symbols reserved by <iso646.h>

[Paul Eggert]

Another fixup inspired by the Beebe build feedback.

2006-02-01  Paul Eggert  <address@hidden>

        Work around portability problems summarized by Nelson H. F. Beebe in
        <http://lists.gnu.org/archive/html/bug-bison/2005-09/msg00021.html>.

        * lib/bbitset.h (struct bitset_vtable): Rename members not, and,
        or, xor to not_, and_, or_, and xor_, respectively.  This works
        around a bug in GCC 3.4.3 on Irix 6.5, which apparently has a
        random system header somewhere that includes the equivalent of
        <iso646.h>.
