gcc 2.96 build

[Paul Kienzle]

I got a successful build out of RH 7.x gcc 2.96!  

It passes all the usual tests.

I needed three changes:

(1) Placement delete is soon to be resolved.

(2) The compiler was consuming many hundreds of 
megabytes of ram to initialize the map in octave_config_info.  
In the current build I just comment it out, but
I have converted it to build the map from an array of
pointers to strings.  I will send a patch to toplev.cc
when I know that it works.

(3) file-io uses std::auto_ptr which isn't available.  The
following batch converts it to use OCTAVE_LOCAL_BUFFER.

        * file-io.cc: Use one less feature of the compiler.
        OCTAVE_LOCAL_BUFFER is used elsewhere, auto_ptr isn't.
