Okay, that much I expected.  But it still doesn't tell enough to know
how to correct this.  We need more info, see below.

Thanks for the info.  This shouldn't by itself cause problems, though,
since all versions above 7.0 are treated the same, provided the
version isn't 10.x (which is reserved by OS/2's DOS emulation).

What ar command line fails, and with what error message?

I need to know where exactly does _rename fail, and why.  Please take
a look at _rename's source near line 110: if the file Y already
exists, it deletes it and tries again.  Please step with GDB through
that code and see what isn't working.

It's possible that it will be easier for you to compile _rename.c with
-DTEST and use the small test program produced by that to look into
this.  That is, use the following commands:

       gcc -DTEST -g -o _rename _rename.c
       gdb _rename.exe
       break _rename
       run test.000 test.001

(assuming test.001 already exists).

Once again, thanks for working on this.
