The YYSTYPE mechanism works fine.  However, you have to read the yacc
manual very carefully to figure it out.  Read page 22 very slowly!
The key statement is the second sentence of the last paragraph on the
page: you MUST use "%type" statements.  If you do that, yacc removes
the three lines it uses to define YYSTYPE, and replaces them with
an appropriate union declaration. If you don't then even if you have
used the "%union" construct yacc insists on leaving YYSTYPE as an
integer by default.
