usage.

  stuff added a few weeks ago.  Turns out that if you specify --proxy-ntlm and
  communicate with a proxy that requires basic authentication, the proxy
  properly returns a 407, but the failure detection code doesn't realize it
  should give up, so curl returns with exit code 0. Test case 162 verifies
  this.

160 shows.

We got no data and we attempted to re-use a connection. This might happen if
the connection was left alive when we were done using it before, but that was
closed when we wanted to read from it again. Bad luck. Retry the same request
on a fresh connect!

Deleted the sockerror variable again, it serves no purpose anymore.

length limit of the hostname part of the URL.

instead to make it easier to find/read

sessionhandle to make the duphandle() function work as supposed. Also tried
to start document functions the doxygen way (in the headers of the functions).
Can't make it work though...

is now treated as an error by libcurl

with Digest or NTLM. libcurl will now use HEAD to negotiate the authentication
and when done perform the requested POST.

Curl_strerror() that attempts to be thread-safe _and_ works on Windows too!

if large file support is available

CURLOPT_POSTFIELDSIZE option to allow really big HTTP POSTs.

make the progress meter more accurate for large files. Also made the sprintf
usage in that function avoid floating point.

argument passing and try to convert to double only when providing data to the
external world.

defines are in setup.h.

the plain old FILE typedef.

it disconnects the TCP connection, like a good ftp client should!

it collides with another MAX define on some platforms (like netbsd 1.6.1)

this allows the HTTP code to *not* return a failure just because no data
has been received from the server

so that the automatic testing hosts will test these changes over the weekend.
