partly bracketed initializer ?


Howdy--

egcs-1.1.1 on Solaris 2.5.1.

If I -D_PTHREADS on my compile lines, and use -Wall, I get
warnings such as :

/usr/local/gnu/include/g++/stl_alloc.h: In instantiation of `__default_alloc_template<true,0>::__node_allocator_lock':
/usr/local/gnu/include/g++/stl_alloc.h:383:   instantiated from `__default_alloc_template<true,0>::lock::~lock<true, 0>()'

/usr/local/gnu/include/g++/stl_alloc.h:565: warning: aggregate has a partly bracketed initializer

The code in question looks like:

#ifdef __STL_PTHREADS
    template <bool threads, int inst>
    pthread_mutex_t
    __default_alloc_template<threads, inst>::__node_allocator_lock
        = PTHREAD_MUTEX_INITIALIZER;
#endif


Where PTHREAD_MUTEX_INITAILIZER is defined in /usr/include/pthread.h

	as

#define       PTHREAD_MUTEX_INITIALIZER       {0, 0, 0}       /* = DEFAULTMUTEX */

So I'm wondering...

What is a partly bracketed initializer warning?

Should I be concerned?

Is the a -Wno-bracketed-initializer to turn them off if I'm 
not concerned?

Thanks for taking the time.
