I see you didn't installed that and when I tried it it still had problems on 
Solaris, since it defined a shell function fn_grep and attempted to use it as a 
command in subprocesses or via Makefiles, which doesn't work.

The whole thing was a bit flaky, and after thinking about it I'd prefer it if 
makefiles and scripts use the just-built 'grep' only when testing grep, not when 
building grep. If the just-built 'grep' is wrong, it can cause the build to go 
awry in subtle ways and this could be trouble. Coreutils doesn't use its 
just-built 'cat' when configuring or building itself, and Grep should do 
likewise with its just-built 'grep'.

So I boldly installed the attached patch, which fixes the problem in a 
more-conservative way. Although this places a minor burden on people building 
GNU Grep on Solaris, these days those folks can easily install a working grep 
from the standard Solaris distribution, which they probably should be doing 
anyway in order to build other GNU packages.

If you see any problem with this please feel free to revert it.
