That would surely break if you were looking up symbols by ordinal 
instead of by name. I didn't even know you could do that until I 
read the documentation for GetProcAddress closely - turns out the 
name parameter can be used as an ordinal.

All exportable symbols are exported by their mangled name in to 
the DLL's export table. Resolving by mangle will give you a 
similar experience to *nix there.
