    HPUX: Disable positional I/O
    
    Some versions of HP-UX have the pread() and pwrite() functions, but
    they behave in odd ways; most notably, ignoring the offset argument
    when _FILE_OFFSET_BITS is defined to 64.
    
    This is noted in recent gnulib documentation
    <http://git.savannah.gnu.org/cgit/gnulib.git/tree/doc/posix-functions/pwrite.texi>,
    and slightly less clear references to pread() being broken can be
    found on the development mailing list for git itself.
    
    It is not completely clear what specific HP-UX versions are affected
    by this. An autoconf run-time test may also be insufficient, because
    the same binaries should be usable on machines with broken and
    non-broken pread() implementations. So, to be safe, disable positional
    I/O on HP-UX unconditionally.
