Comment (by catalyst):

 Oh, a close reading of C99 §6.6 does imply that could be a problem.
 Address constants should be OK, though, so making `var_type_dummy` an
 instance of a union of pointers to all possible types and using named
 member assignment with the address of the member of the static object
 might work?
