From d794ecc9efbcfa044947fd20468ba1f184b357e7 Mon Sep 17 00:00:00 2001 From: David van Moolenbroek Date: Tue, 30 Sep 2014 17:26:43 +0000 Subject: [PATCH] Replace NetBSD grep with OpenBSD grep The NetBSD version is seriously broken--it is unable to match lines against an empty pattern--and appears to be unmaintained. The new version is the latest OpenBSD grep, with a number of MINIX- specific changes marked as such, and an additional number of (signed/unsigned, const) fixes to pass compilation. Since this is not NetBSD code, move back the entire thing into minix/usr.bin.
