In general, I beleive you are right.

But in this case, there are two options:
1) don't use multibyte support on HP-UX 11.11 with gcc
2) futz with _XOPEN_SOURCE on this platform

So I want to try this hack in custom.h (which is appended to config.h):

/* For HP/UX with gcc */
#if defined(hpux) || defined(_HPUX_SOURCE)
/* ... */
#if defined(HAVE_MBRLEN) && defined(HAVE_WCHAR_H) && defined(HAVE_WCTYPE_H)
#undef HAVE_MBRTOWC
#define HAVE_MBRTOWC 1
#define _XOPEN_SOURCE 500
#include <stdarg.h>
#endif

So even though AC_FUNC_MBRTOWC would not set HAVE_MBRTOWC, as mbstate_t
is not available, custom.h would cover it up this way.

In any case, no other platform then HP-UX would be affected.

(But, of course, I don't know whether Arnold would accept this hack.)
