------- Comment #4 from sje at cup dot hp dot com 2006-09-13 21:08 -------
The underlying problem here is twofold, The C++ configure script will only
check for mbstate_t if wchar is enabled. On IA64 HP-UX wchar is not enabled
because we are missing a define that makes the wchar type visible to g++. Here
is a patch that will fix this problem. I have not submitted it yet because we
are in regression only mode.
This patch will make wchar enabled and correctly set GLIBCXX_HAVE_MBSTATE_T.
The extra .o file that we link in is to make sure that we have the correct
unix98 behaviour for the C++ wide date functions and not the unix93 or unix95
behaviour. The C++ testsuite will have regressions if we do not include it.
