Hi Paul,

Thanks for fixing this bug. However, I don't see a test of HAVE_MBRTOWC.
According to gnulib/doc/posix-functions/mbrtowc.texi, the function
mbrtowc() is not available on
  HP-UX 11, IRIX 6.5, Solaris 2.6, mingw, Interix 3.5,
and gnulib provides no replacement. You may want to use the same
substitutes as in gnulib/lib/quotearg.c (which is known to work on all
platforms).
