  The fragment needs to find confdefs.h, so we also link or copy this file into
  the new directory.

+ But AS_LINENO_PREPARE causes the fragment to exit after reloading itself (to
+ prevent the whole script from running twice).  So we change "exit" to "return"
+ in AS_LINENO_PREPARE in the fragment to tell the shell to stop executing the
+ loaded script.

  In summary, this patch temporarily changes $as_myself to refer to the
  fragments, enters a new directory in the build area (since the preconfigure
  fragment will write a modified copy of itself to configure.lineno in its
- current working directory), and makes a copy of confdefs.h in the new
- directory.  All this allows the fragments to be properly preprocessed and
- breaking the loop.
