Portability problems not fixed by Gnulib:

• This function is missing on many platforms: glibc 2.9, macOS 14, FreeBSD 14.0, NetBSD 10.0, OpenBSD 7.5, Minix 3.1.8, AIX 5.1, HP-UX 11, Solaris 11.4, Cygwin 3.4.x, 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.
