Bugs and portability issues in the test suite have been fixed.

Some errors in translations have been addressed, and --help now directs

Stray Info files shipped by accident are removed.

Incorrect definitions of YY_, issued by yacc.c when no parser header is

generated, are removed.

All the generated headers are self-contained.
