I have to correct what I said here: Solaris' /usr/bin/grep doesn't
support -q. So I would like to add this test back in configure.ac (my
original test was probably broken BTW, or I would have noticed earlier).

Additionally, configure.ac itself uses grep -q in several places, which
breaks on Solaris. There are two approaches to workaround this:

1* Test grep -q first, and use $GREP after that.

2* Replace uses of grep -q with grep >/dev/null 2>&1.

What's the prefered way?

Thanks,
