HEXOCTUNSIGN

Message        The HP C compiler conforms to the C standard and will
               give this constant an unsigned type.  Some older
               compilers may give this constant a signed 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 will treat this
               constant as having a signed type.

User Action    Be aware of this difference if you plan to port this
               source to an older compiler.
