9 Portability problems fixed by Gnulib:
13 Portability problems not fixed by Gnulib:
16 This function exists only on Linux and is therefore
17 missing on older glibc versions and many non-glibc platforms:
18 glibc 2.9, Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 11.4, Cygwin, mingw, MSVC 14, Android 4.4.
20 On platforms where @code{off_t} is a 32-bit type, this function may not
21 work correctly across the entire data range of files larger than 2 GB.
22 The fix is to use the @code{AC_SYS_LARGEFILE} macro.
