This is the stock GNU grep 2.4d file.

This is the stock 2.3 file (+ FreeBSD id). Since someone majorly SPAMMED
the repository by NOT vendor importing the virgin 2.0 sources, CVS had no
idea what to do here.

Back out the botched attempt to update to gnu grep 2.3 (lots of history
was lost). Restore original version to try and avoid breaking the build
while David O'brien does a proper set of imports and merges.
