If the variables are in a C file, they can only be static initialised. They're 
either zero-initialised or initialised to a particular value. 

There's no dynamic initialisation. That only happens in C++. And please avoid 
it in C++ too. It increases the load time requirements and the initialisation 
order between different .cpp files ("translation units") is undefined. Also, 
strictly speaking, we should have the main() function in a .cpp file so that 
pre-main initialisation could be done, but the GCC ABI (the IA-64 C++ ABI) 
does not require that.
