| Portability problems not fixed by Gnulib: |

| This function is missing on some platforms: |
| Minix 3.1.8, Cygwin 1.5.x, mingw, MSVC 14, Android 6.0. |
| @item |
| On platforms where @code{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 @code{AC_SYS_LARGEFILE} macro. |
