  * Always do 'setup makefile' before building each library
  This forces preprocessing to happen, which is necessary if any of the
  .hsc files have been modified.  Without this change, a 'setup
  makefile' would be required by hand after a .hsc file changed.
  Fortunately 'setup makefile' isn't much extra work, and I've made it
  not overwrite GNUmakefile if it hasn't changed, which avoids
  recalculating the dependencies each time.
