JSON Superobject not working on Linux

[snorkel]

I am using the exact same version of Lazarus on win32(0.9.30.4-0/FPC 2.6.0) and Linux(ubuntu 12.04) and the JSON super object (http://code.google.com/p/superobject/) won't compile on Linux, compiler generates this error:
(works fine on win32)

/home/components/superobject/superobject.pas(154,18) Error: No matching implementation for interface method "IUnknown._AddRef:LongInt; CDecl;" found
/home/components/superobject/superobject.pas(154,18) Error: No matching implementation for interface method "IUnknown._Release:LongInt; CDecl;" found
/home/components/superobject/superobject.pas(858,1) Fatal: There were 2 errors compiling module, stopping

In 2.6.0 the base COM IUnknown interface definition changed. See

http://wiki.freepascal.org/User_Changes_2.6.0#IInterface.QueryInterface.2C_._AddRef_and_._Release_definitions_have_been_changed
 
Strangely enough some methods look fixed, but not all of them. It might also be that the mix of features causes the problem.

Thanks,  I got it working.  Had to change a couple of functions to use cdecl instead of stdcall.
