Proposed resolution:

This wording is relative to N4971.

1. Modify [headers] as indicated:

   -9- [support.c.headers], C standard library headers, describes the effects of using the name.h (C header) form in a C++ program. The name.h form is the corresponding C header form.

2. Modify [compliance] as indicated:

   -2- A freestanding implementation has an implementation-defined set of headers. This set shall include at least the headers shown in Table 27 and the corresponding C header form ([headers]) of each of the C++ headers for C library facilities (Table 25) included in Table 27.

Set priority to 3 after reflector poll. Some discomfort requiring `errno.h` and `wchar.h` to be freestanding in C++ when they are not in C23. `string.h` is not freestanding in C17, but is in C23 (but C++ is still based on C17). `stdlib.h` is "conditionally partially freestanding" in C23, but not in C17. Suggestion to incorporate this into P3348.

There are many C-ish <cfoo> headers in freestanding. There isn't anything that requires the matching C <foo.h> headers to be in freestanding.
