/* Since there is no official public mscorlib.h header file, and since
* generating your own version from the elusive binary .tlb file takes a lot of
* hacking and results in a 3MB header file (!), we opt for this slightly
* voodoo approach. The following is just enough definition to be able to
* reach the _AppDomain::CreateInstance method that we need to use to be able
* to fire up .Net objects. We used to use IDispatch for this, but it would
* not always work.
*
* The following info was obtained using OleView to export the IDL from
* mscorlib.tlb. Note that OleView is unable to generate C headers for this
* particular tlb... hence this mess.
