   Actually I found a different problem (although I believe the one I mentioned still holds, but just in another case which wasn't mine): the library files are built by just doing "ar crs lib.a objs...", which will simply append the object files to the existing .a file. When a .o is not built anymore, the .a will still include it and generate a "multiple definitions" error. In this case the solution would be to redefine the `ARCHIVE` macro as:
   
   <pre>
   define ARCHIVE
           $(RM) $1
           $(AR) $1 $(2)
   endef
   </pre>
   
   Do you think it is correct to do so? This ensure the .a file is of only object files passed as parameter.
   
   EDIT: OK, I see some cases where ARCHIVE is used multiple times to aggregate different sets of object files. Anyway, it is an easy fix to replace with a single call with a single set of all object files.
