 Hmm, two issues here:

1. Does it really matter given that the actual purpose of these fallback 
   declarations is to address the case where there are no respective 
   system-header declarations or prototypes in the first place (assuming 
   of course that e.g. sizeof (unsigned long) equals sizeof (unsigned 
   int) where applicable)?

2. How does it play with -Werror that we use? -- these "function
   declaration isn't a prototype" warnings will be turned into errors 
   defeating the purpose of these fallback declarations.
