Thanks for the report.
wcwidth is supposed to be declared in wchar.h,
but the above suggests something is not working.

Does your lib/wchar.h file look ok?

Here's the relevant part of mine from a Fedora 12 system:

    /* Return the number of screen columns needed for WC.  */
    #if 1
    # if 0
    #  undef wcwidth
    #  define wcwidth rpl_wcwidth
    extern int wcwidth (wchar_t);
    # else
    #  if !defined wcwidth && !1
    /* wcwidth exists but is not declared.  */
    extern int wcwidth (int /* actually wchar_t */);
    #  endif
    # endif
    #elif defined GNULIB_POSIXCHECK
    # undef wcwidth
    # define wcwidth(w) \
        (GL_LINK_WARNING ("wcwidth is unportable - " \
                          "use gnulib module wcwidth for portability"), \
         wcwidth (w))
    #endif
