How to open 800Mb file

Mon May 17 20:06:16 UTC 2004

Hello,
Please somebody help me, I have corrupted Inbox file (very big one 800Mb)
and I need to open it (possibly with mc), but during opening "F4" I'm
getting message:
"File is too large: Inbox
increase edit.h:MAXBUF and recompile the editor.
"
I have found MAXBUFF variable in edit-widget.h changed it form 1024 to
102400 but it did not work.
So what, where and to what value change to be able to open and edit by hand
corrupted 800Mb file.
I would appreciate any help.

Best regards
