in the Watcom makefiles aren't quite correct).

renamed generated config.h to curl_config.h in order to avoid clashes when libcurl is used with other projects which also have a config.h.

  setting a file descriptor non-blocking. Used by the functionality Eric
  himself brough on June 15th.

  (http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
  problem:

  Url A is accessed using auth. Url A redirects to Url B (on a different
  server0. Url B reuses a persistent connection. Url B has auth, even though
  it's on a different server.

  Note: if Url B does not reuse a persistent connection, auth is not sent.

Markus Koetter provided a patch to avoid getnameinfo() usage which broke a couple of both IPv4 and IPv6 autobuilds.

to use the "standard" ENABLE_IPV6 one. Also, if port number cannot be figured
out to connect to after a name resolve (due to it not being IPv4 or IPv6),
that particular address will now simply be skipped.

  range if given colon-separated after the host name/address part. Like
  "192.168.0.1:2000-10000"

  don't know how they got wrong in the first place, but using this output
  format makes it possible to quite easily separate the string into an array
  of multiple items.

sclose() function-like macro definition used to close a socket,
now solely based on HAVE_CLOSESOCKET and HAVE_CLOSESOCKET_CAMEL
config file preprocessor definitions.

  provided in the url, add it there (squid needs this).

  contributed a range of patches to fix them.

With the curl memory tracking feature decoupled from the debug build feature,
CURLDEBUG and DEBUGBUILD preprocessor symbol definitions are used as follows:

CURLDEBUG used for curl debug memory tracking specific code (--enable-curldebug)

DEBUGBUILD used for debug enabled specific code (--enable-debug)

Revert delegating c-ares linking magic on libtool and auto-makefiles when using
the uninstalled c-ares libtool archive built from the CVS embedded tree.

This embedded c-ares linking is again handled from the configure script.

  is almost always a VERY BAD IDEA. Yet there are still apps out there doing
  this, and now recently it triggered a bug/side-effect in libcurl as when
  libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
  knows it will just get a 401/407 back. If the app then replaced the
  Content-Length header, it caused the server to wait for input that libcurl
  wouldn't send. Aaron Oneal reported this problem in bug report #2799008
  http://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix.
