Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: AIX 5.1, mingw, MSVC 14.

  * On platforms where f_blocks in struct statfs is a 32-bit value, this function may not work correctly on files systems larger than 4 TiB.  The fix is to use the AC_SYS_LARGEFILE macro.  This affects Mac OS X.
