 The rtems_build_name() is implemented by:
 {{{!c
 #define  _Objects_Build_name( _C1, _C2, _C3, _C4 ) \
   ( (uint32_t)(_C1) << 24 | \
     (uint32_t)(_C2) << 16 | \
     (uint32_t)(_C3) << 8 | \
     (uint32_t)(_C4) )
 }}}
 If the name is build from four "char" components, then the result depends
 on the signedness of the char type. The macro should first cast the chars
 to uint8_t.
