// 06-16-94 AlexT Add FnAssert prototype
// 07-26-94 AlexGo Added CStabilize and CSafeRefCount
// 21-Dec-94 BruceMa Wrap mbstowcs and wcstombs
// 23-Jan-95 t-ScottH added Dump method to CSafeRefCount
// 08-Sep-95 murthys Added declarations for compapi worker
// used by com, stg, scm etc
//
// Notes:
// There are two versions of ole2int.h in the project. This is
// unfortunate, but would be a major pain in the butt to fix.
// What I have done is to extract the share parts of the two files,
// and put them in this file. ole2int.h then includes this file.
//
// Someday, somebody should reconcile all of the differences between the
// two ole2int.h files, and rename them. Don't have time for that now,
// so I have gone for the path of least resistance.
