Could you please give an example of the "fiddly" bit? I list the URLs
to use with the install and it's clearly labeled "The last version of
Cygwin that supports XP is 2.5.2-1". Or were you, perhaps, refering to
the actual usage of the URL in the Setup program?
Another user, Michel, responded that perhaps a more explicit message
with exact steps for install this might be helpful (as the "Dead Simple
Instructions" are generic), but I'm not sure it's really necessary. Is
that, perhaps, what you are refering to in that the instructions aren't
explicit enough?
