I suppose my situation is different, but am I the only person who uses the 
Windows-native FINDSTR utility?

(require 'compile)
(setq grep-command "findstr /n ")

The syntax is of course completely different, and there are certainly 
significant RegExp differences, but it ignores the "NUL" that appears at the 
end of the command so basically works and its syntax is similar-enough to 
grep's that I can mostly forget which one I'm using.  (I'm a programmer, so 
generally am searching for a single word such as a function name....)  

I just add the /S option when I want recursive descent behavior....
