#3 function declaration

[Sjoerd Meijer]

Compilation failed on my Fedora Core 6 system with GCC
version 4.1.1. In file

src/rte/cosy/cosynetwork.cc

functions are called without being defined yet:

fatal_func
clean_func
zero1_func
zero2_func
zero0_func

Moving these functions to the beginning of the file
or defining them solves the problem.
