I forgot to include the PR number in my ChangeLog entry but this defect is
fixed with the patch in comment #4.  It has been backported to the 4.0, 4.1,
and 4.2 branches as well as being checked in on the ToT.

[Bug target/28975] conflicting declaration 'typedef struct mbstate_t mbstate_t'

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.

So that means when __STDC_VERSION__=199901  then _GLIBCXX_HAVE_MBSTATE_T needs
to be defined or something like that.

Anyways this is a target issue.

Thanks!

Adding -D_GLIBCXX_HAVE_MBSTATE_T to the compile line gets around the error.
