| Release 3.2: April 22, 1999
| 
|      New feature: <valarray> header, as defined in section 26.3 of the C++
|      standard. 
|      <limits> header is now supported on compilers that lack support for
|      constant initialization of static const data
|      members, such as Microsoft v6.0. 
|      Performance improvements in copy for compilers that lack support for
|      partial specialization of templates. 
|      Improved support for insert_iterator when used with hash tables and
|      slist. 
|      Documentation bug fix: documentation now makes it clear which library
|      features are standard and which are SGI
|      extensions. 
|      Bug fixes.

| Hm. Now we have two basic_strings and two valarrays...
| Perhaps in a near future we will have two free implementations of libstdc++?

Great!

I'm just back and I've good news.
As far as I can tell, SGI implementation of <valarray> seems to be a
"trivial" one (more or less vector<>). It remains to see how effective
it's in real numerical computations. 

Anyway, now we have two implementations to experiment with :-)
