People still use Solaris! On Solaris, GNU diff is called 'gdiff'. Some of our

code (particularly in the perforce client) handled this, but the check to make

sure that we were using GNU diff didn't.

I haven't had access to a Solaris machine in over a decade (eep), so I couldn't

test that part, but I ran the unit tests to make sure I didn't fudge up

anything else.
