Build fix

Detail:
  s.makehswis used to pull in various IO header files. There was no good
  reason for this, and doing so causes a dependency upon Hdr:Machine.<Machine>
  to define which generation of IOC/IOMD is in use - which is a problem if
  the C library is to be built where Machine=All.
Admin:
  Tested in a Machine=All build.
