 Here's a proposed patch to install.texi to document the problem.  Note
 that I've also removed the obsolete assertion that one must configure
 with --disable-multilib on non-buggy systems.

 I think it would be greatly appreciated if you could generate a small 
 patch for the target specific installation instructions!
 
 Thanks

 Yes.  The current patch revision is 112963-05, dated 2002-12-06
 (available from <ftp://sunsolve.sun.com/pub/patches/112963-05.zip>).
 If the workaround for Sun bug 4747851 is correct, this should
 fix the problem.  However, I haven't verified this, and also
 the Sun database still lists the bug as not being fixed.

 Yes, that's what I'd do.

    Paul, in your report you mention a patchset from Sun that was
    not available at the time. Did this situation change in the
    meantime?
    
    I may not understand the problem in all details, but it
    appears to me that there is little value to have a bug
    report about a situation we cannot do anything about. The
    only thing I see is that we might want to document the
    problem in the target specific installation instructions.
    
    Thanks
      Wolfgang
