I am about to check it in.  In the future, please apply all changes to 
both versions of crt0.S (one in newlib, one in libgloss).  It is my 
eventual goal to remove the sys/arm directory in newlib.  I have 
applied the changes to the one in libgloss.  Please take a look and ensure 
that it is correct.
