There are only 2 remaining compiler warnings and all failing test cases are explained below
```
```
/Users/ckrey/mosquitto/src/sys_tree.c:274:50: warning: format specifies type 'unsigned long' but the argument has type 'int64_t' (aka 'long long') [-Wformat]

27 tests still fail (I sorted out the python environment problem with the `psutil` module)
- the known problem for the sqlite persistence test cases
- broker-01-bad-initial-packets
In macOS the client sometimes detects `BrokenPipeError` instead of `ConnectionResetError`.
If we handle both exceptions, the test is successful:
```

- broker- 08-ssl-bridge and client-03-publish-tls
before we can use this address to test the `—insecure` TLS connection.
```
sudo ifconfig lo0 alias 127.0.0.2 up
```
- broker-16-config-huge
The `bind_interface lo` is not valid on macOS because the default loopback device is `lo0`, not `lo`.
- client-subscribe-format
The last 2 test cases fail because `mosquitto_sub` exits with the following error message:
```
% /Users/ckrey/mosquitto/builddevelop/client/mosquitto_sub -p 1888 -q 1 -t 02/sub/format/test -C 1 -V mqttv311 -F "%.3f"
Error: Can't print float, missing __STDC_IEC_559__ standard support.

```
Because this test in `client_shared.c`
```
164 #ifndef __STDC_IEC_559__
165 fprintf(stderr, "Error: Can't print float, missin
