I have taken this step with 1.3.3, but I am still hampered by the now
identified gdb bug, which is what is really holding me back now.  Now 
that I know that 1.3.3 is not going to play nice with gdb under a Win2K 
workstation in an NT domain (is that qualified enough for you  ;~), I 
need to go back and get a copy of the last 1.3.2 source and build the 
augmented dll there.

If you can get the gdb bug fixed, even as a slipstream patch that I 
will have to apply myself, I can work vs 1.3.3.  Otherwise, the only 
thing I can do go back to a known configuration and try and work 
forward in time.

I'm not running 1.3.3, I am running 1.3.2.  I do not lightly accuse
CygWin of being at fault.  But I have tried Perl distributions known to
have tested clean before, and they now core during the cleanup phase.  
So if the application behavior has changed, but the application has 
not, that is very strong evidence that the underlying code (being 
CygWin) has to be the primary suspect.  It might not be cygwin1.dll 
itself; it may be gcc that is messing up an optimization, or it may be 
some other library that was updated in the last 3 months.

I may have to go back in time and install only those modules of CygWin
available in early July and then, assuming I can get clean builds, 
slowly work forward until everything goes south.
