Note that some systems do not have statvfs.  This is the case of,
for example, NetBSD until 2.1, which only had statfs (sys/param.h and
sys/mount.h required for it to work).

>From statvfs' manpage:

HISTORY
     The statvfs(), statvfs1(), fstatvfs(), and fstatvfs1() functions
first
     appeared in NetBSD 2.1 to replace the statfs() family of functions
which
     first appeared in 4.4BSD.
