--- Comment #4 from Mike Franklin <slavo5150 at yahoo.com> ---
`std.c` is a package.  `std.c.stdlib` is a module within that package.

Analogously, `core.stdc` is a package and `core.stdc.stdlib` is a module within
that package.

If your code used to use `std.c.stdlib` then you need to replace it with
`core.stdc.stdlib`, not `core.stdc`.
