State-Changed-Why:
    Do you have any way to try this with a later release of
    gcj?  2.95.2 is rather old, unfortunately.
    
    It is possible that this problem is fixed in the cvs
    version of libgcj.  Or, maybe it isn't.  I don't know,
    because I'm not set up to use Cygwin.  We don't do
    Cygwin builds of libgcj on a regular basis.
    
    If you can try the cvs libgcj, and it still fails,
    could you perhaps do any debugging of it?  It might be
    as simple as adding the appropriate #ifdefs in parts of
    the code.  Basically, any more data would be useful here --
    we'd like to fix this, but don't really have the resources
    to do all the investigation right now.
