I almost certainly can, and it does sound like a good idea.

I can't test the resulting patch, though (having no access to a Windows 
machine), and our Windows developers can better choose the symbol to use 
(AFAICT the situation with libraries possibly being absent at runtime is 
solely Windows-specific).

Step 2 might be to propagate the same error-signaling behavior to other 
features, like xml.c.
