Sure there is. Emacs can do it (I just tried it). It's quite slow, but 
it works. And even if it didn't work, core commands like 'diff' 
shouldn't arbitrarily limit themselves to small files.

No doubt 'diff' can be fixed to work even on MS-Windows platforms. 
However, arbitrarily limiting line numbers to 32 bits is not the way to 
go about it.
