This allows environment variables to be safely exported using show-environment

to do something like

logind: when setting a new controller, don't prepare the VT if logind is restarted

When assigning a new session controller to a session, the VT is prepared so the
controller can expect the VT to be in a good default state.

However when logind is restarted and a session controller already took control

the VT state set by the controller.

Each enumerated type shall be compatible with char, a signed integer type, or
an unsigned integer type. The choice of type is implementation-defined, but
shall be capable of representing the values of all the members of the
enumeration.

and 7.16.1.4:

The parameter parmN is the identifier of the rightmost parameter in the
variable parameter list in the function definition (the one just before the

a function or array type, or with a type that is not compatible with the type
that results after application of the default argument promotions, the behavior
is undefined.

This might cause a real issue if the compiler chooses something that is not an
integer for ExtractFlags. Rework the code to avoid the warning, but add an
