"maximum buffer size exceeded" error

Hi All,
I am trying to work on text files in excess of 180 Mb.  When I try to open 
the file I get the above response (in quotes).

Is there a way to set the maximum buffer size so that I can open these 
bigger files?

Thanks,
Dan Simon,

I think not yet. The problem is that the file is accessed in Lisp. The 
Lisp pointers are too short, less than 32 bits, 28 bits, which 
corresponds to 256 MB. Could be it's better in GNU Emacs 22 (from CVS) 
or in Unicode Emacs 23.

Without vi there is only GNU Emacs

In 32bit systems, It's 128MB on Emacs-21.  It'll be 256MB on Emacs-22.
It can be made 512MB fairly easily (patch not provided, tho).

But it can also be made insanely large by recompiling on a 64bit system.
This "insanely large" is the theory.  Practice will probably bump into bugs
when crossing the 2GB limit.
