Portability problems fixed by Gnulib:

Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: Mac OS X 10.3, OpenBSD 3.8, mingw, MSVC 9.

  * On platforms where f_blocks in struct statvfs 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 glibc/Hurd, HP-UX 11, Solaris.
