My program scans all Idl files to create a Delphi unit
containing all 
constants (adapting constant names and declarations to
Delphi syntax). 
My program did not expect these constructs in the Idl file:

const long TABLE = com::sun::star::sdb::CommandType::TABLE;
const long QUERY = com::sun::star::sdb::CommandType::QUERY;

Of course it is possible (but more complex) to recognize a
constant from 
another Idl, but what would you do if it refers to an Idl
file that you 
have not yet scanned ? Forward reference may become a real
problem if 
this kind of dependency is widely used. Will we need a make
file for Idl 
files ?

There should be an include directive in the file, pointing
to
CommandType.idl. So your tool probably should scan included
files, too.
This shouldn't be a problem, since cyclic references should
not happen
(else the regular IDL compiler would already complain).
