Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on many non-glibc platforms:
glibc 2.9, macOS 14, FreeBSD 6.0, NetBSD 7.1, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.3, Cygwin 1.7.1, mingw, MSVC 14, Android 4.4.
But the replacement function is not atomic; this matters in multi-threaded
programs that spawn child processes.
