Detail:
  HdrSrc is such an unusual component that the only shared makefile
  fragment it uses is StdTools. Almost every line requires edits to
  accommodate the differences between amu and GNU make, so for clarity
  we use separate makefiles for the two tools.
Admin:
  I'd forgotten that I'd created the XCompile branch a few years back
  until just now! I think this is a superior solution because it confines
  the changes to a single file, at least in the short-term.
