curl is a library needed only for the remote access netCDF OPeNDAP
client, which is optional.  If you do not need to access data from
remote OPeNDAP servers through a netCDF interface, and if you were
building from source on cygwin, then you would not need the curl
library.  However, since you are just using the NCO prebuilt Windows
binary for Cygwin, it apparently was built with OPeNDAP enabled, so it
needs the curl library.  So, you need both Cygwin and the curl library.

That is a configuration file for the "udunits2" library, to handle
units of measurement.  It's already present in the main Linux distos
since March 2011, according to this announcement, which also has a URL
from which it can be downloaded separately:

  http://old.nabble.com/-ITP--udunits-2.1.21-1-td31079247.html

Probably NCO doesn't just include the udunits2 library as part of the
NCO package, because it's already included in recent Linux distros,
so there's no need to build and install it again ...

I think just a Cygwin environment variable, although I'm not sure what
the difference is, because I don't use Windows.

Good luck, I hope this works.
