silence warnings under macOS for cc, clang and gcc
Used the following script to check for warnings
not silenced via ${CSILENCE}:
```sh
find ???? -mindepth 1 -maxdepth 1 -type d | while read dir; do
(cd "$dir"; echo =-=-= "$dir" =-=-= ; csilence -v 1 clobber all ; echo ; csilence -v 1 clobber alt)
done 2>&1 | less
```
