Thanks.  Sorry I didn't notice that people had asked the same question before.

We should probably fix the documentation:

   https://cygwin.com/cygwin-ug-net/using-cygwinenv.html
   https://cygwin.com/cygwin-ug-net/dumper.html

Or maybe we should just remove all mention of dumper from the documentation.
Given that we're trying to move people away from 32-bit Cygwin, I don't think it 
makes sense to document a feature that works only on the latter.

Ken
