Huh. Must be my vstools install on this windows laptop is out of date or broken 
in some other way. I could copy the scheme in that use case into my PR for at 
least a non-zero chance that it would match the msvc mangler in all other 
instances triggering that if. I must say that the thought of digging through 
the msvc binary to get a comprehensive handling does not feel me with 
excitement.

I love the idea of another triple though. I would of course be using itanium if 
interfacing with system resources was not impossible. I'm thinking of two 
possible interpretations of a hybrid triple:
* msvc for all non-templates, itanium for all templates. Also causes any 
explicit extern template instances to be ignored to prevent the already remote 
possibility that a specialization or instance could be provided by a library 
(which would of course be mangled msvc-style).
* an `__attribute__ ` or other intrinsic to specify (in a header file) that an 
alternate mangler is to be used for the single connected symbol. As much as I 
hate the idea of compiler-specific code features, sometimes they are the right 
answer.

I prefer the former.
