Busybox 1.13.2 and df -h problems

[Lloyd Sargent]

I built a system using Buildroot for the AT91SAM9261 processor and it works 
great -- except that when I type "df -h" I don't get human readable output.

Here is an example:

# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root                 5304      2620      2684  49% /
tmpfs                    30936         0     30936   0% /tmp
# df -h
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root                 5304      2620      2684  49% /
tmpfs                    30936         0     30936   0% /tmp

This used to work in older versions of Busybox (1.2.1) -- is this a known 
issue? 

Cheers,

Lloyd
