Thanks to both of you for replying. Sorry for not replying to you
earlier.

Daniel, it does do that, thank-you. I wasn't sure though whether that
proved it had the support previously provided by the separate DLLs...
I'd guessed that would depends on whether curl.exe loaded all the
DLLs it might need at the start of its execution (in which case maybe a
-V call would fail if they couldn't be found) or only when one/all of them
were actually needed.

That Dependency Walker thing has cropped up in quite a few threads
I've read in various places recently... I must install it and play with it...

I've tried this with the same results. Thank-you for your detailed
and clear explanation.

Oops, I thought when I read that... I hadn't looked at 'the' readme in the
download. But I have done since then. But, the 'binary' download (as
is mentioned in various Stack Overflow threads - I'm glad I'd read those
first) isn't at all what a normal Windows user would expect.

Mine has 40 files in 21 folders. Twelve or so of those files have 'README'
in their names, and that doesn't include the MANPAGE and INSTALL files.
Almost none of these files (all of which I looked at before writing this)
have any relevance to a Windows user.

Quite a lot of them have no extension in their filenames, making them a
pain to open and read on Windows... every one needing a right-click and
a choice of editor. Those that do have extensions are ".MD" which is also
not associated with anything on a typical Windows system.

The curl.exe file is found inside a folder named "src" which is probably
the last place anyone 'knowledgeable' would ever look...

The first time I downloaded this and unzipped it I was sure I'd somehow
got a source download with makefiles etc... and immediately deleted it
and looked again at the choice of downloads. But lots were like that;
that's when I went off to Google and hence Stack Overflow...

 It'd be a lot less intimidating if one merely downloaded a zip containing
curl.exe, a licence file & the CHANGES file (but both with a .txt extension)
and a short relevant-to-Windows help .txt file.
