Yes. As mentioned in the original plfs hint the reason for using the
included regex was that the old grep-2.5.1 would fail 1 test when using
the Glibc regex of the day. That was, um, "fixed" in grep-2.5.1a.

Of course, the current Glibc regex is reputed to be much better and less
buggier than earlier incarnations.

Not only that, using the Glibc regex results in a smaller grep binary :-)

Thanks for bringing this up.
