Hi,

I am using libcurl to do a multipart post with the curl_formadd() function, but
it bugs in some cases (I use libcurl 7.10.6 with Linux slackware 9).

I get the same error with the multi-post.c example if I modify the source
to keep the "Expect:" header, i.e. I comment these lines:

     //struct curl_slist *headerlist=NULL;
     //char buf[] = "Expect:";
     //headerlist = curl_slist_append(headerlist, buf);
     //curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headerlist);
     //curl_slist_free_all (headerlist);

(actually, commenting just the line 68 with curl_easy_setopt() is enough)

Here is what I get :
--------------------------------------------------------------------------------------
antoine_at_tech04 /<2>src/curl-7.10.6/docs/examples> multi-post localhost/cgi-bin/test
* About to connect() to localhost:80

< HTTP/1.1 100 Continue

--------------------------------------------------------------------------------------

There is no problem if I remove the "Expect:" header or if the server sends back
an "405 Method Not Allowed" instead of the "100 Continue".

Any idea?

BTW, I also found an other little bug in function:

CURLMsg * curl_multi_info_read( CURLM *multi_handle, int *msgs_in_queue);

If the function returns a NULL pointer, msgs_in_queue is not set to 0. It can
be confusing if this variable was initialised with a value different from 0.
