Responsible-Changed-Why:
    Just marking that I am no longer working on this problem
    (sorry to have kept it assigned to myself for so long
    with no final progress).
    
    In general, a complete fix requires moving all control from
    gcc/config.gcc to gcc/configure.in .  It would be better
    to provide all legal values (and a hint for the default
    for the target) for --enable-threads in gcc/config.gcc
    and centralize the seclection of the thread model after
    config.gcc is parsed.  You will note that the control
    logic is currently spread to the following locations:
    - before config.gcc is parsed (in configure)
    - per-host in config.gcc with much duplication and
      many annoying subtle differences
    - after config.gcc is parsed (back in configure)
    
    When the user specifies a value for --enable-threads that
    is not legal for the target or specifies --enable-threads
    without a value and the target default is single; the
    "early configure" should abort with a clear message.
    
    A patch was posted that handles the second issue without
    moving all the control logic as should (IMHO) be done.
    It moved most control logic related to thread model
    selection within configure to after config.gcc was
    parsed without touching config.gcc.  This less than
    ideal improvement was never fully accepted or rejected.
