I already have the Feb 22 distribution, because you told me to get it 
when I couldn't find STL.  STL is in that distribution, but valarray is 
not.  I also checked libstdcx.a with nm and a grep for 'array', but again 
nothing (not unexpected since it's not declared in any header).

Similarly, auto_ptr is not defined anywhere in lgp271b.zip or on the SGI 
(which does have STL and libg++ 2.7.1), another Draft C++ Std template  
class.  I don't know what else might be missing.

I've already started implementing valarray from the std, and afterwards 
I'll probably make the auto_ptr class as well.  Again I'ld be happy to 
make them available when they're done if someone else doesn't do it first.

Thanks for the reply.
