Hmmm.... yes

Rereading the language of section 6.9.2 of the C standard (or at least the 
draft I could find, since I seem to have mislaid my copy of the C89 standard 
:-) ), the tentative declaration only is only required to remain tentative to 
the end of a file.

I guess this means this approach won't work if gcc -fno-common (or another 
compiler which behaves like that) is used.

So, I suppose I need to change this to use a functional interface to 
initialize ddxHooks.
