Thanks for the warning, Igor.  I set it in the .cmd file which starts my cygwin.
To make sure I just ran a test case by writing a program that crashes.  dumper started
as supposed to.  But it wrote an empty core file.... :-(

Anyway, what next to try with perl?  Could it have anything to do with threads?
I just had the problem when I tried to build perl on VMS.  Threads and 64bit stuff
wouldn't work.  Just a thought.

Michael
