f_bavail; is not a documented feature of IRIX's statfs but actually
thinking about it it would be better to use statvfs() which does
(http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/statvfs.h.html)

However do all OS's have a concept of two different answers to how
much free space there is, and what would an application developer want
to know, if I'm writing a 'df' style application then I might want
both. I guess the available space for the user is more interesting..
but then you get into quota's etc.
