In the manual, document where POSIX.1-2024 allows namespace pollution. Although it might be nice to add something like GNULIB_POSIXCHECK to detect when Gnulib-using code is unportable in this area, I don’t offhand see a good way to do that.

POSIX.1-2024 allows, but does not require, this file to make visible
|
|
all symbols from the header @code{<stddef.h>}.
|
|
Programs should not assume that these other symbols are visible merely
|
|
because this file is included, or that they are invisible because only
|
|
this file is included.
