Placing a comma should be OK if there are chances the struct or enum will 
ever grow. This prevents later patching the line to add the comma, 
possibly creating confusion about who is the author of that line.

On the other hand, no comma at the end of an enum or struct memeber that 
we want to always be the last one (COUNT_OF_WHATEVER_OPTIONS, 
custom_data_area[], etc.) helps avoiding trivial errors as it forces one 
to add that comma to compile the code.
