'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.
