HEXOCTSIGN

Message        In VAX C mode, the compiler will give this constant a
               signed type for compatibility with VAX C.  This
               differs from the behavior specified in the C
               standard, which would give this constant an unsigned
               type.

Description    The C standard specifies that an octal or hexadecimal
               integer constant has an unsigned type when its value
               cannot be represented in a signed integer type, but
               can be represented in the corresponding unsigned
               integer type.  Some older compilers, such as VAX C,
               will treat this constant as having a signed type.  In
               VAX C mode, the compiler matches the behavior of VAX
               C.  In other modes the compiler matches the behavior
               specified in the standard.

User Action    Be aware that this difference may cause porting
               problems if this program is compiled in a mode other
               than VAX C mode, or with a compiler that does not
               support this old behavior.
