Ehmm...  I see that test/src/buffer-tests now have 5 failures that
were not there before:

  5 unexpected results:
     FAILED  test-buffer-modifications
     FAILED  test-kill-buffer-auto-save-default
     FAILED  test-kill-buffer-auto-save-delete-no
     FAILED  test-kill-buffer-auto-save-delete-yes
     FAILED  test-restore-buffer-modified-p

Also, 7 of the lisp/files-test fail:

  7 unexpected results:
     FAILED  files-tests-bug-18141
     FAILED  files-tests-file-name-non-special-make-auto-save-file-name
     FAILED  files-tests-file-name-non-special-set-visited-file-modtime
     FAILED  files-tests-no-file-write-contents
     FAILED  files-tests-revert-buffer
     FAILED  files-tests-revert-buffer-with-fine-grain
     FAILED  files-tests-zzdont-rewrite-precious-files

Could you please look into these?  (Interestingly, those 5+7 don't
fail for me on MS-Windows, only on GNU/Linux...)
