Curiously, the grep on FreeBSD seems to be GNU's grep with some additional
patches, though I expect that it's a ways behind whatever GNU is releasing
now, because while they were willing to put some GPLv2 stuff in FreeBSD,
they have not been willing to have anything to do with GPLv3. FreeBSD's grep
claims to be version 2.5.1-FreeBSD, whereas ports has the gnugrep package
which is version 2.27, so that implies a fairly large version difference
between the two. I have no idea how they compare in terms of performance.
Either way, I would have expected FreeBSD to be using their own
implementation, not something from GNU, especially since they seem to be
trying to purge GPL stuff from FreeBSD. So, the fact that FreeBSD is using
GNU's grep is a bit surprising. If I had to guess, I would guess that they
switched to the GNU version at some point in the past, because it was easier
to grab it than to make what they had faster, but I don't know. Either way,
it sounds like Mac OS X either didn't take their grep from FreeBSD in this
case, or they took it from an older version before FreeBSD switching to
using GNU's grep.
