Portability problems not fixed by Gnulib:

  * This function exists only on Linux and is therefore missing on older glibc versions and many non-glibc platforms: glibc 2.9, macOS 11.1, FreeBSD 14.0, NetBSD 9.0, OpenBSD 6.7, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11.4, Cygwin 2.9, mingw, MSVC 14, Android 4.4.

  * On platforms where off_t is a 32-bit type, this function may not work correctly across the entire data range of files larger than 2 GB. The fix is to use the AC_SYS_LARGEFILE macro.
