[Octave-bug-tracker] [bug #63573] Build warnings from curl library

[Arun Giridhar]

Follow-up Comment #6, bug #63573 (project octave):

I'm still getting a gcc warning


In file included from ../liboctave/util/url-transfer.cc:44:
../liboctave/util/url-transfer.cc: In member function 'virtual void
octave::curl_transfer::form_data_post(const
Array<std::__cxx11::basic_string<char> >&)':
../liboctave/util/url-transfer.cc:737:17: warning: 'CURLOPT_HTTPPOST' is
deprecated: since 7.56.0. Use CURLOPT_MIMEPOST [-Wdeprecated-declarations]
  737 |         SETOPT (CURLOPT_HTTPPOST, mime);
      |                 ^~~~~~~~~~~~~~~~

      |   ^~~~~~~~~~~~~~~~~


but I'm more confused by the fact that the structure pointer "mime" is never
changed to something other than nullptr before it is used. Where is mime
assigned to a valid mime struct?
