[C++-sig] Specified procedure could not be found

[Niall Douglas]

Doesn't matter if you use it, if it's linked then something you're 
using is using it.

If it isn't lazy linked, just one failed symbol import will fail the 
whole DLL dependency tree. No idea what might cause that in your 
case, maybe there's a mixing of different versions of system DLLs by 
various dependencies. Welcome to DLL hell!

I'd suggest you eliminate dependencies until the problem goes away. 
Start by lazy linking anything not absolutely necessary (though this 
pushes the fatal exit into the runtime).

Also, check a fresh install of Windows inside a virtual machine. 
You'll often find the problem isn't there, in which case it's a 
problem on your development machine. Maybe time for a wipe and 
reinstall if that's the case, saves time in the long run.
