0bb28106be Fix for tickets #32 and #33: Generate the names of the result set early, before 
doing the flattening optimization or evaluating subqueries.  Otherwise, the
result set column names are generated incorrectly or after they are needed. (CVS 553)

08192d5f76 Fix for ticket #31: Do not attempt the flattening optimization if the

a WHERE clause is constant. (CVS 548)

41202ccae2 Fix for ticket #22: In the code generator for compound SELECT statements, take 
care not to generate column name headers if the output is an intermediate table.
Otherwise the column headers are not generated correctly if a compound SELECT
statement appears as an expression in part of the WHERE clause. (CVS 543)
