Perhaps I spoke out of turn.  I was using MC++ to make a bridge between
the CLI and native C++ code.  Based on my experience and on information
received from the Mono developers, this type of assembly contains a
small amount of x86 native code that calls Win32 functions.  IIRC, it is
used for initialization purposes.  Being able to use this assembly on
Linux or other platforms where Mono is available requires some form of
Win32 emulation.  I had thought that Jonathan would have used a similar
route to reduce the amount of coding overhead for a .NET-aware BGL.  A
pure Managed C++ BGL would not include the native code, as I understand
it.

I should also note that my experience comes from roughly one year ago
using Visual C++ 7.0.  I have not tried to compile my Managed C++ code
with VC++ 7.1.  I just assumed it produced similar results.
