I suggested this to Dirk Heinrichs (the author of the orignal bug report),
but it didn't work.  Please see and

I am not qualified to judge this, but I guess that Paul's suggestion might
be true.  If you (Thomas) are willing to work with Dirk Heinrichs to find
a solution (and if D.H. still has spare time to help GNU), I'd be interested
to hear the results.

So it seems that the only known fix at the moment is to include the header.

For now, I'm not able to invent better solution then this:
1) update the configure script to use AC_FUNC_MBRTOWC; this effectively
   disables multibyte support on hosts with this problem.
2) document the hack with including sys/_mbstate_t.h in README.hpux .

Unless a better solution is found, I'll submit this to the gawk maintainer.

Thank you,
