I have stored out new versions of thttpd, mini_httpd, http_get, and oauth_sign. The change is the same in all of them: handle more HTTP methods besides the usual GET/HEAD/POST. This was necessary because of one new call in the Twitter API that requires HTTP DELETE, for no good reason.
I also stored a new version of http_post to accomodate a different new Twitter API call that needs a new non-standard content-type.
