This sounds like my doing.  What version of Oracle are you using?
Oracle 9i has a bug that interferes with the documented mechanism for
asking Oracle for the type of an SQL statement (i.e. whether it is a
query returning row data, or a statement that modifies rows).  So I
asked David James for a quick fix that consisted of checking the
beginning of the SQL for either "select" or "with".

We could be more sophisticated about parsing things, I guess skipping
over any arbitrary combination of comments and white space.  Or, if
you're using a version of Oracle not affected by the bug, you can edit
src/Makefile and comment out the line:

  WORKAROUND = "-DRS_ORA_SQLGLS_WORKAROUND"
