Portability problems not fixed by Gnulib:
@itemize
@item
This function is declared in @code{<winsock2.h>} instead of @code{<arpa/inet.h>}
on some platforms:
mingw, MSVC 14.
@item
POSIX.1-2024 says this function is obsolescent and it is planned to be
removed in a future version.
Use the function @code{inet_ntop} instead.
@item
The @code{inet_ntoa} function need not be reentrant, and consequently
is not required to be thread safe.  Implementations of
@code{inet_ntoa} typically write the timestamp into static buffer.
If two threads call @code{inet_ntoa} at roughly the same time, you
might end up with the wrong date in one of the threads, or some
undefined string.
@end itemize

Note: @code{inet_ntoa} is specific for IPv4 addresses.
A protocol independent function is @code{inet_ntop}.
