Wonderful links and information!!

That is all I really needed, since I assume 1.5 is basically no longer
being developed, I don't see a big need to create mappings for the
shadow volumes.  I do think it would be good to have the above links
and documentation added to the special names section of the
documentation.

Time to experiment with Cygwin 1.7

I know the whole package is still considered test.  How stable is the
actual dll(s).  Especially as relates to this type of functionality.

Thanks
Greg
