Re: mbswidth.c portability fix for UnixWare 7.1.1

[Paul Eggert]

2003-02-28  Paul Eggert  <address@hidden>

        * lib/mbswidth.c: Include <wchar.h> before "mbswidth.h", to work
        around a UnixWare 7.1.1 porting bug reported by John Hughes in
        <http://mail.gnu.org/archive/html/bug-bison/2003-02/msg00030.html>.
