Certain Delphi constructs are not yet supported by the FreePascal preprocessor. Therefore, I have written a patch to implement this functionality, so the package Technetium can compile on FreePascal again.

The attached patch closes both these bugs:

If you accept this patch, please give credit as something like this: "Patch by Christian Iversen to implement symbolic constants and the IN operator in the preprocessor"

It seems that the real delphi uses a different approach to parsing expressions in the preprocessor, so eventually this patch will be replaced. However, for now, it helps many projects compile that otherwise wouldn't be able to.
