NONINTENUM

Message        <Context> the enumeration type, and all associated
               enumeration constants will have type <type> because
               at least one enumeration constant had a value that
               could not be represented in the type signed int.

Description    The standard requires that enumeration constants have
               a value representable as an int.  Other C compilers
               will allow enumeration constants to have values
               outside this range.  In some modes the HP C compiler
               will allow this extension.  To identify exactly which
               constants are outside the range, enable the
               nonintenumcon message.

User Action    Be aware that other compilers may not support this
               extension.
