This is very dangerous. You must make absolutely sure that MSL is linked 
before PythonCore, and that there's no way your hosting program can ever 
satisfy a reference to an external from the GUSI-enabled MSL in 
PythonCore, or very bad things will happen.

If I understand this correctly the only thing needed, aside from what is 
installed by the "developer" option in the installer already, is a 
PythonCore.lib stub library, right? That should be reasonably simple: an 
extra "stub library" project in PythonCore.prj should do the trick.

An advantage of this might be that we could possibly also create a 
PythonCoreNoMSL.lib stub library which is the same stub library but with 
all MSL symbols removed. This would make life easier for the case where 
you want to embed Python into a non-GUSI application.
