One thing that might be happening, is the libstuff.a(myroutine.o)
defines one or more symbols that your version does not.  If any
of these symbols are referenced by anything else that is linked in,
the linker will still bring in the version from the library, which causes
the conflict with your routine.  You need to change your version
of myroutine.o so that it contains its own version of all public symbols
in libstuff.a(myroutine.o).
