I've been poking around the www.GNU.org site in search of a current
grep executable for Win/DOS, but without much luck--the GNU world
seems to to have gone all Linux...

Specifically, I use an old verison of MKS ToolKit grep that does not
recognize the -A and -B command line options, which I need.

Any help/suggestions/links much appreciated.
