This is one of those days with a brand new curl release. Curl and libcurl
7.7.2 is mainly a bugfix release.

Get curl 7.7.2 from http://curl.haxx.se/download.html. As usual, allow some
time before the popular binary archives are up-to-date with this.

This release includes the following fixes:

 o 'curl-config' is a new tool to aid applications to know where libcurl
    is installed, what features it has built-in and what libs it requires
    when linked with etc. curl-config is created at build time, use --help
    to view available options. There's also a man page written.
 o Updated perl interface. Now supports callbacks and many more options.
 o Resumed download on persistant connections were bugfixed
 o Trying to resume a FTP download that is already complete now returns a
   newly defined error code
 o Time conditions in HTTP headers could use wrong time zone.
 o Minor #include fix to build properly on Ultrix
 o The environment variable HTTP_PROXY in uppercase is no longer understood,
   as it may cause security problems when used in CGI environments and similar
 o The progress meter was not properly reset between transfers using a
   persistant connection
 o CURLOPT_HEADERFUNCTION is a new libcurl option that makes a separate
   callback function get called when headers are being written.
 o curl_escape() now works as documented with a length argument saying 0
 o The version string shows "OpenSSL 0.9.6a" properly
 o curl_formfree() doesn't choke on a NULL input
 o The Host: headers could get wrong on persistent connections
 o Borland makefiles updated
