 When i use the web-browsing access to the CVS source, i find this in
 v1.1 of stdstream.cc:
 
 ----------------------------------------------------------
 struct _fake_ostream {
        ....
 };
 
   .
   . 
   .
 
 #ifdef __GNUC__
 #define OSTREAM_DEF(NAME, SBUF, TIE, EXTRA_FLAGS, ASM) \
   _fake_ostream NAME ASM = { {&NAME.base}, {STD_STR(SBUF, TIE, EXTRA_FLAGS) }};
 #else
 #define OSTREAM_DEF(NAME, SBUF, TIE, EXTRA_FLAGS) \
   _fake_ostream NAME = { {0, &NAME.base}, {STD_STR(SBUF, TIE, EXTRA_FLAGS) }};
 #endif
    .
    .
    .
 
 OSTREAM_DEF(cout, COUT_SBUF, NULL, 0, )
 ----------------------------------------------------------
 
 what i am not seeing ?
