This is df2, an alternate df-like utility for System V.
It needs mnttab.h and sys/statfs.h, so it probably will only
work for S5R3.  I've never used ustat() but it may be an
alternate way to getting it going under earlier OSes.

Simple to compile:  cc -O -o df2 df2.c
             make df2 (if you are in a directory with no [Mm]akefile)
Simple to use: no options, just say
               df2

Sample output:
