first off .. staggering response time. I have often filed bug reports ot 
testsuite reports on various GNU tools/projects and seen them vanish into a 
black hole. Other times we get a proper bug report and then can work on it and 
very very rarely my hair gets blown back by a reply. Guess what my hair is 
doing now ?  :-)

So let's seee, firstly I did install the grep anyways with the assumption that 
I had an edge case here and I should let you know that the grep that I was 
using to build this grep was /usr/xpg4/bin/grep on Solaris. I hope that makes 
sense. 

So let's see here : 

$ echo $LC_ALL
C
$ mkdir a
$ echo x | truss -o tr /usr/local/bin/grep -f a/

$ cat tr

Not sure how that helps there.
