The reason I want it is that right now my source files are coupled (one source 
file has to know which other source file(s) include exitcode.h, in the worst 
case I get a lot of header files coupled to each other just because one end 
of the chain needs an include file which in turn includes exitcode.h.

This problem is related to the fact that in C++, you often split classes into 
their own .h/.cc file pairs, it's very very uncommon to put everything into 
one file.

No, it's not necessary for exitcode.h, that header file does not provide any 
functions.
