Sure.

Yes, I fixed it and checked my fix into CVS :-). BTW, that is the
one we are discussing now.

With the current linker from CVS,

# make
....
Running: ldd threadtest
        libthreadlib.so => ./libthreadlib.so (0x40019000)
        libc.so.6 => /lib/libc.so.6 (0x4002a000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x4013e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
Running: ldd test
        libthreadlib.so => not found
        libc.so.6 => /lib/libc.so.6 (0x40028000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

If you think there still is a problem, please send me a testcase
to show it.

Thanks.
