Thanks for the detailed instructions. I have a few comments, based on my
Cygwin experience.

I don't think this should be necessary. I routinely use the bugfix.all
file, without change, on cygwin. So, try the instructions as written first.

You should not have such mixed formats. This looks like you somehow set up the
AMBERHOME variable with backslashes, even though your email indicates that you
did not do that. You really don't want things like "C:\" in your variables,
and this never happens to me.

I have never had the need to do this. For me the test suite works without any
changes.

It should be very helpful. My advice is to first try things as in the
instructions, and if they fail, look at some of the fixes Bob lists here.

...thanks...dac
