    cpdup(1): Minor cleanups
    
    * In 'cpdup.h', remove an inaccurate comment about <strings.h>
      inclusion.
    * Change predefined macro '__linux' to '__linux__', meanwhile add an
      empty define of '__dead2' under '__linux__' scope.
    * In 'hcproto.c', put static variable 'chflags_warning' inside
      '_ST_FLAGS_PRESENT_' macro scrope.
