Detect and prevent multiple declarations with the same identifier. (from MathCore)

[krsta]

In OpenModelica it possible to have multiple declarations with the same identifier in the same scope without the kernel complaining. For example the model below is accepted by the kernel, and not even when checking the model the error is detected.

model A
 Real x;
 Integer x;
end B;

One could also have a component in a class and an inherited component with the same name but different type:

model A
  Real x;
end A;
model B
  extends A;
  Integer x;
end B}}}
Both forms of the bug fixed in revision 5196.

Reopen. There are at least two testcases that could be added here. The original in the description, and the one in the comment above. But no testcase is added! What is not tested is not implemented!

There is still a problem with the Rotational.Examples.Friction model:
