Portability notes:
-* `std::size` is not available in C++98. Use the `array_length`
- template function in src/include/lib.h instead of `sizeof` and
- dividing. Types passed to template functions cannot be anonymous in
- C++98; in other words, the "tag" of a `struct` or `enum` type must not
- be empty.
+* `std::size` is not available in C++98. Use `countof()`, which is
+ provided by the gnulib module `stdcountof-h` and expected to be
+ standardized in C2y, instead of `sizeof` and dividing.
* C++98 lacks value initialization for array types.
