Testcase to demostrate problem..

I am enclosing a testcase which demonstrates the problem.  Essentially it just
dumps the contents of a couple of tables - the SQL for each has a condition on
it of some sort.

To run, simply run "msidump <msifile>" where you pick some msi file that you
happen to have lying around.  The theory is that the output of the program
should be identical if you are running on windows and under Wine if you are
using the same msi file.

On real Windows, I see it able to dump information from the Component,
InstallExecuteSequence, CustomAction and Media tables.  But because of the
problem I noted where strings can only be compared for equality, the
MsiDatabaseOpenView call fails for the Dialog and ControlEvent tables.

On ReactOS (using Wine dlls), the CustomAction, Media and Dialog tables are
dumped.  There is no output for the Component and InstallExecuteSequence tables
for reasons that are unknown.  The call to MsiDatabaseOpenView call for the
ControlEvent table fails here in the same way as under real windows.

If you want me to upload a compiled binary of this testcase, I can do that
