a) For curl, I looked at the list of packages specified at:


   and chose the one described as:

   "Win32 2000/XP  7.25.0  binary  SSL  SSH  Gunter Knauf  1.52 MB" 

b) for wget, the binaries & dependencies zips described at

And how do I tell what that is, when one set have no version numbers?

The sizes of the two versions of the two libs are significantly different,
with the no-version-number ones being about 50% bigger than the versioned
ones.  I would have thought that successive releases of these pretty
standards libs (I've seen them embedded in other apps) would be of simialr
sizes.  I wondered if one pair might have been compiled differently, if that
makes sense.

Jeremy C B Nicoll - my opinions are my own.
