The __getcwd symbol only exists in glibc 2.0, not in libc5 or glibc 2.1.
If you have a mixed glibc/libc5 system you will get the avove error when
running libc5 apps.

If you only intend to use the libgetcwd.so on Linux 2.2.x systems you
can easily fix the problem by applying this diff:

--- xfs/linux/getcwd.c.orig     Fri Feb 19 18:45:51 1999
+++ xfs/linux/getcwd.c  Fri Feb 19 18:46:12 1999

     retval = sys_getcwd(buf, size);
     if (retval >= 0)
        return buf;
-    if (errno == ENOSYS)
-       return __getcwd(buf, size);
     else
        return NULL;
 }
