gcc-2.95.2 on alphaev6-dec-osf5.1

[psz at maths dot usyd dot edu dot au (Paul Szabo)]

Dear GCC people,

I successfully built gcc-2.95.2 on:

% ./config.guess
alphaev6-dec-osf5.1

I did have a few problems though, please see below: hopefully you can fix
these for the next release. (Please let me know if you need more details.)

Cheers,
