'size' for susan_edged_mod_1 .o files 
 
33 = pre 3.3.3-suse (hammer branch 
40 = CVS head 20050209 
patched = CVS head 20050209 with the 'TER hack' patch applied.

ppc32: 
   text    data     bss     dec     hex filename 
   2780       0       0    2780     adc 33.o 
   3348       0       0    3348     d14 40.o 
   3140       0       0    3140     c44 patched.o 
 
So for ppc this bug is still not fixed even with my patch.  Interesting data 
point is the ppc32 size with -Os -fno-ivopts: 
   2820       0       0    2820     b04 no-ivopts.o 
 
So perhaps the pending IVopts patches will also help for this problem.
