[fpc-pascal] parameter names local, global, glocal

I've seen this before while doing ports from delphi to freepascal. What I did, just
to get it quickly working,  was use the underscore, although a bit messy looking:

  function SubstringData(const Offset, Count_: Integer): WideString; virtual;

  procedure ReplaceData(const Offset, Count_: Integer) ...

or

  function SubstringData(const Offset, _Count: Integer): WideString; virtual;

  procedure ReplaceData(const Offset, _Count: Integer) ...
