This is the stock 2.3 file (+ FreeBSD id). Since someone added 2.0 rather than vendor importing the virgin 2.0 sources, we have to manually put this on the HEAD branch. 1999-11-20 23:42:44 +00:00			`/* Emulate getpagesize on systems that lack it. */`
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. Requested by: obrien 1999-11-20 09:40:28 +00:00
