Since you have an enum, why not make the variable have enum type too?
If you don't want to give the enum a name/tag, there's always:

static enum
 {
   ...
 } run_mode = RUN_DAEMONIZE;

As principle, making the type an enum makes the code easier to debug,
as "(gdb) print run_mode" then outputs the enum value (RUN_DAEMONIZE, etc.)
instead of the underlying integer (0, 1, etc.).

GNU style is against such redundant parenthesis.
