Thanks. I applied this patch to my local copy of the Axiom
Silver build_improvements branch.

You are right. So in addition to your change to
'gcl-2.6.8pre/o/unixfsys.c' in delete_file:

        if (unlink(filename) < 0 && rmdir(filename) < 0)
                FEerror("Cannot delete the file ~S: ~s.", 2,
                  path, make_simple_string(strerror(errno)));

and I added the following to rename_file:

#ifdef HAVE_RENAME
        /* Make sure we can rename */
        if (unlink(newfilename) < 0) rmdir(newfilename);
        if (rename(filename, newfilename) < 0)
                FEerror("Cannot rename the file ~S to ~S.",
                        2, vs_base[0], vs_base[1]);
#else
...

I am testing the build now.

Thanks.

Bill Page.
