It converts on the -u. I don't know about -H since the TPF port is only for
FTP at present and -H shows up as an HTTP option.

Right. I had lucked out on the calls but it's not a good solution moving
I'll work up a better fix in April.

Actually, Daniel's suggestion was for the curl_[un]escape functions, which
are now curl_easy_[un]escape and do take CURL*.
The unescape_elements function is internal to ldap.c.
I noticed that ldap.c used void* internally and followed suit.
I can easily make it a CURL* but that seemed a bit incongruent to me.

I'll change that to #define VERSION "not-used" to mimic config-vms.h.
I noticed config-riskos.h #undef's it. I'm not sure which approach is
It doesn't seem to matter either way.

Doh! CURL_ICONV_CODESET_FOR_UTF8 shouldn't have been copied into src/main.c

And I too don't like defining it in two different places.
But I couldn't find a header file that lib/easy.c and src/main.c share,
which is the logical place to put it.

And the platforms that use conversion will be well aware of it.

I know very little about threads. What would be a good solution?
Would moving the _cd fields to the SessionHandle make this thread safe?

I was following the current code, which uses a '.' for unprintable
characters but that's easy to change if it's useful.
