Thanks for the response, but (as you point out) I neglected to mention
that this is for a DECStation 5000/200.  Thanks also to those who
have suggested GNU Emacs/GCC alloca(), but it works (doesn't work :-)
in the same manner as the DEC alloca() -- the storage allocated is
not IN the stack.  I had already tried it before I posted.

I am still looking for an (assembly) version of alloca() which
does manipulate the stack to allocate storage.
