Comment (by knarf):

 I don't understand your comment about VError and the noreturn attribute.
 The idea of that macro is to be variadic, much like CCTK_VWarn already is
 - to be able to compose nice error messages depending on something
 dynamic. It wouldn't change anything about the noreturn attribute.

 Currently CCTK_WARN a function (through a #define). CCTK_ERROR (and
 CCTK_VError) could be the same, but could also contain (within a block) a
 call to exit - something a compiler hopefully sees as 'noreturn' without
 even using that attribute. That call wouldn't ever be executed ...
