LONGEXTERN

Message        The external identifier name exceeds <number>
               characters; truncated to "<truncated spelling>".

Description    The length of an identifier with external linkage
               exceeds the maximum allowed on this platform.  The
               name used in an output object file will be truncated
               to meet the platform restrictions.  Note that the
               debugger name will be unchanged.

User Action    Reduce the size of the name.  On OpenVMS platforms
               the /NAMES=SHORTENED qualifier can also be used.
               When the qualifier is specified, the compiler will
               encode long external names instead of truncating
               them.
