POSIX specification:@* @url{https://pubs.opengroup.org/onlinepubs/9699919799/functions/wcsncmp.html}

Gnulib module: wcsncmp

Portability problems fixed by Gnulib:
@itemize
@item
This function compares the wide characters as if they were unsigned, although
@code{wchar_t} is signed, on some platforms:
glibc 2.14.1 on x86 or x86_64, musl libc 1.2.3, macOS 12.5, FreeBSD 13.2, NetBSD 9.0, OpenBSD 7.2, Solaris 11.4.
@item
This function may return a wrong result if the two arguments are of different
length, on some platforms:
AIX 7.2 in 64-bit mode.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On Windows and 32-bit AIX platforms, @code{wchar_t} is a 16-bit type and therefore cannot
accommodate all Unicode characters.
