KOBJMETHOD: use better construct in the checking version of the macro
Big thanks to Christoph Mallon for the idea/code!
This construct has benefit of sticking much stricter to C standard and thus
keeping more compilers happy as Clang doesn't like the current construct
because it doesn't treat FUNC != NULL as a compile-time constant.
The checking version is still under 'notyet'.
