    Issue 3554: Avoid empty grammar rules using @$ for getting a source  
location

    Several rules use @$ for getting the source position from an empty
    rule, but Bison does not even provide a source position for empty
    rules.

    This patch fixes most cases by letting different non-empty rules
    assign the respective source positions.  The case of #{ #} cannot be
    fixed in that manner since there is not a single token providing a
    source position in the whole production.  Fixing this particular case
    would require a different technique.
