Bison patches to avoid GCC 3.2 warnings on Solaris 8.

[Paul Eggert]

configure --enable-gcc-warnings caught some minor problems, and I
installed these fixes.  I suppose the xstrdup might cause a memory
leak, but it's a minor one.

2002-10-19  Paul Eggert  <address@hidden>

        * src/muscle_tab.c (muscle_pair_list_grow): Rename locals to
        avoid confusion with similarly-named more-global.
        * src/output.c (prepare): Use xstrdup to convert char const *
        to char *, to avoid GCC warning.
