OK, a patch doing exactly this is attached to this mail, maybe someone
searching the mail list archive may find it useful.
(It patches directly awkgram.c, so bison is not needed.)

The source has the following:

#if defined(HAVE_MBRLEN) && defined(HAVE_MBRTOWC) &&
    defined(HAVE_WCHAR_H) && defined(HAVE_WCTYPE_H)

So your system has mbrlen(), mbrtowc(), wchar.h and wctype.h but you don't
have wctype_t even if you include wctype.h?
This sounds strange.  How does wctype.h look like?

Please mail us the details about this configuration.

There was a heuristics whether the link is required.  It only checked the
destination directory for a file named awk.

I've changed the check to call "which awk" and "awk --version".  If awk
executable is found and the version info doesn't start with the word GNU, 
the sylink is not created.

The patch is attached. (Again, it patches Makefile.in directly, so you
don't have to search for the right version of automake.)

Sure.

Have a nice day,
