libstdc++ bug - need help (IRIX)

[jarausch at igpm dot rwth-aachen dot de]

Hi,

I still struggle against the basic_stringbug<..>::seekpos problem
While I could resolve the problem on Linux (there were some outdated
_G_config files in /usr/local/include/g++-v3/
the problem still remains on my IRIX box.
When libstdc++ is built the definition of  mbstate_t of
/usr/include/wchar.h gets priority saying
#ifndef _MBSTATE_T
#   define _MBSTATE_T
	typedef char	mbstate_t;
#endif

but when I invoke g++ lateron

/usr/LOCAL/include/g++-v3/bits/std_cwchar.h
redefines it

#ifndef _GLIBCPP_HAVE_MBSTATE_T
extern "C" 
{
  typedef struct 
  {
    int __fill[6];
  } mbstate_t;
}
#endif



although both
/usr/LOCAL/include/g++-v3/mips-sgi-irix6.5/bits/c++config.h
and
/usr/LOCAL/mips-sgi-irix6.5/include/g++-v3/bits/c++config.h
are saying
// Define if mbstate_t exists in wchar.h.  */
#define _GLIBCPP_HAVE_MBSTATE_T 1


Trying to 
#define _GLIBCPP_HAVE_MBSTATE_T 1
in my source files gives lots of compile errors since
it lacks mbstate_t

How to solve this problem?

Thanks for any hints,
