ENUMSANDINT

Message        <Context> allowing an enumeration type and a signed
               int to be compatible may not be portable.

Description    The standard states that enumeration types shall be
               compatible with an integer type.  HP C, along with
               most other C compilers, has chosen the signed int
               type to be compatible with enumeration types.  Other
               compilers may chose another type such as unsigned int
               (the C standard even allows an implementation to
               choose different integer types depending on the
               values of the enumeration constants defined for the
               type).  Therefore this program may not be accepted by
               other C compilers.

User Action    Insert a cast to make the types the same.
