function in the libidn API that I hope we can remove once libidn gets a
function like this.

involved in the curl project! This happens when you try to curl a file from a
proftpd site using SSL. It seems proftpd sends a somewhat unorthodox PASS
response code (232 instead of 230). I relaxed the response code check to deal
with this and similar cases.

  formposts no longer include the path part. If you _really_ want them, you
  must provide your preferred full file name with CURLFORM_FILENAME.

  Added detection for libgen.h and basename() to configure. My custom
  basename() replacement function for systems without it, might be a bit too
  naive...

  Updated 6 test cases to make them work with the stripped paths.

  sense to provide this for more failures in a more generic way, but let's
  start like this.

curl/multi.h header to work better in winsock-using apps.

glibtool was found and used instead of plain libtool.)

  replacement, curl only replaced the Host: header on the initial request
  and didn't replace it on the following ones. This resulted in requests with
  two Host: headers.

  Now, curl checks if the location is on the same host as the initial request
  and then continues to replace the Host: header. And when it moves to another
  host, it doesn't replace the Host: header but it also doesn't make the
  second Host: header get used in the request.

  This change is verified by the two new test cases 184 and 185.
