Problems linking to calloc

[Mark Mussetter]

Thank you for responding so quickly!

That seemed to do the trick for this round of errors.  There was a problem 
in my Arch.rules file.  I had commented out the CFLAGS += .....   line and 
tried to duplicate it with my own requirements.  I must've had a tab 
instead of spaces (or vice versa).  I uncommented the old CFLAGS += 
......  line and changed it to meet my requirements and it worked.

Thanks again,

Mark
