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.
• This function can hang if it stats all preceding entries in /proc/mounts, and any of those file systems are hard-mounted and not available. This affects Linux < 2.6.36.
• 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.

Gnulib provides a module fsusage that provides similar information as statvfs.
