Option flags
Each
option has one or more of the following flags set.
These flags are assigned to the individual options in
optiondefs.h.

#define P_STRING 0x04 // the option is a string
#define P_ALLOCED 0x08 // the string option is in allocated memory,
// must use free_string_option() when
// assigning new value. Not set if default is
// the same.

// never be used for local or hidden options!
