If you're using the avrfreaks make files, then the cause of the problem is
the COFF-generation step; after the generation, this copies all files from
the COFF subdirectory back into the work directory... which causes the
hiccup.

The problem is in the file
  <basepath>avrfreaks\avr-make
in Block 9.

Don't remember how it looked like directly after installation (hey, that was
2 weeks ago :-), but the offending rule was this one (might look slightly
different, I tried to reconstruct it from memory):

%.cof: %.elf
        $(ELFCOF) $< $(OUT) $@ $*.sym
        $(CP) $(OUT)/$@ .
        $(CP) $(OUT)/* .

... which copies ALL SOURCE FILES BACK AGAIN.
I've replaced that by

%.cof: %.elf
        $(ELFCOF) $< $(OUT) $@ $*.sym
        $(CP) $(OUT)/$@ .
        $(CP) $(OUT)/$*.sym .
        $(CP) $(OUT)/$*.S .


Try that...

Bye,
