- When an invalid value for 'taskd.trust' is noticed, the 'sync' command will
error out, and the 'diag' command will refer the user to the man page.
This is because the allowed values were 'yes'/'no', and now are
'strict'/'ignore hostname'/'allow all'.
- Included C++ compiler compliance level. If 'diag' output is then included in
the test suite, we can monitor compliance across platforms, and decide when
to use new features.
