+Subject: [PATCH] core: add flexible member to ares_addrinfo to fix c-ares 1.18
+
+Add a flexible member to account for c-ares 1.18 adding an additional
+`name` member to `struct ares_addrinfo`.  This fixes the following
+exception from cffi, and the resulting test_getaddrinfo* failures:
+
+```
+Exception ignored from cffi callback <function _addrinfo_cb at 0x7f5fa890d040>:
+Traceback (most recent call last):
+  File "/tmp/pycares/.tox/py39/lib/python3.9/site-packages/pycares/__init__.py", line 162, in _addrinfo_cb
+    result = ares_addrinfo_result(res)
+  File "/tmp/pycares/.tox/py39/lib/python3.9/site-packages/pycares/__init__.py", line 841, in __init__
+    cname_ptr = ares_addrinfo.cnames
+ffi.error: struct ares_addrinfo: wrong total size (cdef says 16, but C compiler says 24). fix it or use "...;" as the last field in the cdef for struct ares_addrinfo to make it flexible
+```
