The fix is to #include <stdio.h> before <wchar.h>.
>From lib/mbswidth.h:
/* Avoid a clash of our mbswidth() with a function of the same name defined
in UnixWare 7.1.1 <wchar.h>. We need this #include before the #define
below.
However, we don't want to #include <wchar.h> on all platforms because
- Tru64 with Desktop Toolkit C has a bug: <stdio.h> must be included before
<wchar.h>.
- BSD/OS 4.1 has a bug: <stdio.h> and <time.h> must be included before
<wchar.h>. */
#if HAVE_DECL_MBSWIDTH_IN_WCHAR_H
# include <wchar.h>
#endif
