Rem All fixes needed to get the package configured, compiled and tested.
Rem 1:  Change the stateless-check script so it knowns about the
Rem     new filenames.
Rem 2:  Ditto for Makefile.in
Rem 3:  Ditto for source files.
Rem 4:  Change the files contained in the tests subdirectory from
Rem     UNIX-style EOL into DOS-style EOL so the testsuit works.
