I think that the original idea that the ".y" suffix should be allowed to
vary is wrong, as the input is the same format. This is what causing your

The manual says that --output=<parser-filename> produces a parser file
named <parser-filename> and similarly, --output=<defines-filename> produces
a defines file named <defines-filename>. This is how I think it should be.

If you want to allow suffixes vary, introduce some new options for that.
Users under UNIX can then easy construct their own bison variation by an

So, for example
  bison foo.y --output-suffix=.cc --defines-suffix=""
would produce a parser file named foo.cc and a defines file named "foo",
and so would
  bison foo.yxx --output-suffix=.cc --defines-suffix=""

The default is:
  bison foo.y --output-suffix=.c --defines-suffix=.h
