Portability problems fixed by Gnulib:

• This function is missing on many platforms: musl libc, FreeBSD 9.3, NetBSD 6.1, OpenBSD 6.9, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 10, Cygwin 2.9, mingw, MSVC 14, Android API level 32.

Portability problems not fixed by Gnulib:

• The second argument is of type size_t, not int, on some platforms: FreeBSD, NetBSD, OpenBSD.
• On platforms where the function is missing, the Gnulib substitute implementation is just a stub, and does nothing.
