Two things:

(a) you need to use -v rather than --version

(b) you need to supply an EOF

% /usr/bin/as -v < /dev/null
Apple Computer, Inc. version cctools-525.obj~1, GNU assembler version 1.38

Thanks for the rapid responses. Looking at line 3723 of
glibc-2.3.3/configure shows that it is passing --version
to as:

| ac_prog_version=`$AS --version 2>&1 | sed -n 's/^.*GNU assembler.* \([0-9]*\.[0-9.]*\).*$/\1/p'`

Inserting '< /dev/null' does the trick. Thanks.<!-- ~MESSAGE_AFTER~ -->

First of all, in my case it produces an error (using bash):

dune:~ iang$ /usr/bin/as --version
/usr/libexec/gcc/darwin/ppc/as: I don't understand '-' flag!
Apple Computer, Inc. version cctools-495.obj~4, GNU assembler version 1.38

But then "--version" is not a documented option so using "-v":

dune:~ iang$ /usr/bin/as -v
Apple Computer, Inc. version cctools-495.obj~4, GNU assembler version 1.38

Admittedly it appears to hang at that point, but in fact it is not
really hung. The man page points out that if no files are specified
it reads from stdin, so in fact it is just waiting for you to indicate
EOF by typing ctrl-D. It seems that "-v" means "print version before
starting assembly". Try this:

dune:~ iang$ /usr/bin/as -v < /dev/null
Apple Computer, Inc. version cctools-495.obj~4, GNU assembler version 1.38
dune:~ iang$

Glad it worked. The question I was asking would be a few lines up from
where you were. I wasn't looking for the version command, but how it
determined that it was looking at a GNU build before it even tried to
get the version. The first line in what you posted:

 > checking whether ld is GNU ld... no
 > checking for /usr/bin/as... /usr/bin/as

Standard output is like your butt. Everyone has one. When using a bathroom,
they all default to going into a toilet. However, a person can redirect his
"standard output" to somewhere else, if he so chooses. - Jeremy Nixon<!-- ~MESSAGE_AFTER~ -->
