It looks like the build tools will not warn you (or stop with an error) if 
there are multiple declarations of the same PCD in the DSC file. In fact, the 
same PCD could be initialized multiple times using different values and 
different types (Fixed vs. Dynamic for instance), and the build tools will 
silently pick the last instance of the PCD in the DSC File.

We just finished debugging a nasty issue caused by duplicate PCDs, and it would 
have been nice to prevent this to begin with! Looks to me like a bug in the 
tool.

Can we add the ability to break the build if there are duplicate PCD instances 
in the DSC file?
