------- Comment #2 from paolo dot carlini at oracle dot com  2009-10-23 18:14 -------
Let's CC Rainer. IMHO something is broken in gthr-solaris.h, I see:

#ifdef __cplusplus
#define UNUSED(x)
#else
#define UNUSED(x) x __attribute__((unused))
#endif

...

static inline int
__gthread_mutex_destroy (__gthread_mutex_t * UNUSED(__mutex))
{
  if (__gthread_active_p ())
    return __gthrw_(mutex_destroy) (__mutex);
  else
    return 0;
}

which cannot be Ok when __cplusplus is defined. Not a libstdc++ proper issue.
