        You're on berklix.  ld sez: "undefined: _memcpy".  You say: "who's
        doing that?".  The source is scattered inconveniently.  The
        obvious thing to do is:

        grep -l _memcpy *.o

        That this often will not work is irritating.

    True, grep only works on readable files, the next most obvious thing
    to do is produce ascii output, then grep:

    	nm $i | egrep '_memcpy|:'

Since we are on berklix, there is an even better way:

nm -o *.o | grep _memcpy

The -o flag tells nm to prepend the file name to each line.
This even works on Version 7.

When this doesn't work try sending via uunet.uu.net or mcvax.uucp.
