- David McCreedy provided libcurl changes for doing HTTP communication on 

non-ASCII platforms. It does add some complexity, most notably with more
  #ifdefs, but I want to see this supported added and I can't see how we can
  add it without the extra stuff added.

Changelog
Daniel (14 January 2007)
- David McCreedy provided libcurl changes for doing HTTP communication on
non-ASCII platforms. It does add some complexity, most notably with more
#ifdefs, but I want to see this supported added and I can't see how we can
add it without the extra stuff added.
- Setting CURLOPT_COOKIELIST to "ALL" when no cookies at all was present,
libcurl would crash when trying to read a NULL pointer.
