Why here, but not below in CHECK_AND_CAST?

You would have to ask Matthias :-)
Now wrapped in do while(0) and moved line continuation slashes to column 80.
I also moved the var declaration from the use location to inside the macro.

 
 
 #define CHECK_AND_CAST(type, var, param)                                      \
