commit 89b08e23180c242a058653e246ace2ca47b56a3a
Author: Michael Stahl <mstahl at redhat.com>
Date:   Mon Oct 23 17:43:21 2017 +0200

    curl: upgrade to release 7.56.1
    
    - fixes a very minor CVE: CVE-2017-1000254
    - the Windows nmakefiles we were previously using have been
      removed, so we use the *other* Windows nmake build system now
    - /EHs override is pointless, default /EHsc should work fine
    - the macros defined in ExternalProject are not needed any more
    - curl-msvc-schannel.patch.1: drop, not needed with new makefiles
    - curl-osx.patch.1: none of it applies, presumably fixed upstream

-Subject: [PATCH] macOS: Fixed crash on 10.8 caused by missing connectx()
- function
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The connectx() function call appeared in Darwin 15.0.0
-That covers OS X 10.11, iOS 9 and tvOS 9.
-
-Because connectx is not declared with weak_import attribute it’s not possible
-to build libcurl on OS X 10.11 and later and target systems which don’t have
-_connectx symbol declared in libsystem_kernel.dylib (i.e. OS 10.8 and earlier).
-
-Solution is to use connectx only on platforms that officially support it
-i.e. by defining CFLAGS="-mmacosx-version-min=10.11" in configure step.
-
-Note: It is possible to conditionally use connectx() in libcurl targeting
-range of systems based on availability determined during runtime using dlsym().
-
