It's 2**31, and we don't want arbitrary limits like that in GNU code. It's easy
to generate line numbers larger than that nowadays. Here's a contrived example:
$ rm -f big
$ truncate --size 10TiB big
$ echo x >>big
$ ls -l big
-rw-r--r--. 1 eggert eggert 10995116277762 Feb 12 00:38 big
$ grep -zn x big
10995116277761:x
Although diff is not nearly as good as grep with large files (that 'grep'
command consumes only 4 ms real time on my old office desktop), diff shouldn't
purposely have problems in that area.
You should be able to avoid the problem by compiling with Cygwin.
