Thanks!

We talked about it. I wasn't convinced by my scheme,
but we couldn't come up with a better solution, so we kept that.

For the readers, it wasn't clear, but for the developers of the page,
I wrote a comment at the beginning of the page,
which I hope was clear enough:

.\" Layout:
.\"	A list of type names (the struct/union keyword will be omitted).
.\"	Each entry will have the following parts:
.\"		* Include
.\"			The headers will be in the following order:
.\"			1) The main header that shall define the type
.\"			   according to the C Standard,
.\"			   and
.\"			   the main header that shall define the type
.\"			   according to POSIX,
.\"			   in alphabetical order.
.\"			;
.\"			2) All other headers that shall define the type
.\"			   as described in the previous header(s)
.\"			   according to the C Standard or POSIX,
.\"			   in alphabetical order.
.\"			*) All headers that define the type
.\"			   *if* the type is not defined by C nor POSIX,
.\"			   in alphabetical order.
.\"
.\"		* Definition (no "Definition" header)
.\"			Only struct/union types will have definition;
.\"			typedefs will remain opaque.
.\"
.\"		* Description (no "Description" header)
.\"			A few lines describing the type.
.\"
.\"		* Conforming to
.\"			Format: CXY and later; POSIX.1-XXXX and later.
.\"			Forget about pre-C99 C standards (i.e., C89/C90)
.\"
.\"		* Notes (optional)
.\"
.\"		* See also

But I like very much your "Alternatively, " wording.  I'll use it!

Thanks,

Alex
