This also broke our Solaris build with the following error:

======================================================================
FAIL: testGetaddrinfo (test.test_socket.GeneralModuleTests)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/..../cpython-main/Lib/test/test_socket.py", line 1523, in testGetaddrinfo
    self.assertEqual(repr(type), '<SocketKind.SOCK_STREAM: 1>')
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError: '<SocketKind.SOCK_STREAM: 2>' != '<SocketKind.SOCK_STREAM: 1>'

+ <SocketKind.SOCK_STREAM: 1>
?                          ^

(test.test_socket.GeneralModuleTests fails with the same error).

The issue is almost certainly that on Solaris, SOCK_STREAM is defined as 2 rather than 1; the following simple program confirms that:

#include <stdio.h>
#include <sys/socket.h>

void main() {
	printf("%d\n", SOCK_STREAM);
}

I'm just not sure whether to fix this with `assertRegex` or a special branch for Solaris (though I am not sure whether everybody else uses 1 or it's more varied).
