The tip of my archive is,

I've just upated to,

changeset:   7720:4f903c303c3c

summary:     implement subspace function

... I've removed the -ff2c parameter and built fresh. All tests pass!

My simple test code also works!

	mldivide (2*eye(500) + circshift (eye (500), 1), ones (500, 1));

Regarding the xztodc.f and modified qrupdate,

    1 2008-03-18  John W. Eaton  <jwe at octave.org>
    2
    3         * qrupdate/zqrqhv.f (zqrqhv): Call xzdotc instead of  
zdotc.
    4         * blas-xtra/xzdotu.f: Eliminate local zdotu variable.
    5         * blas-xtra/xzdotc.f: New file.
    6         * blas-xtra/Makefile.in (FSRC): Add it to the list.

I hadn't noticed that change when it was made. It is likely that I  
haven't tried to build with it until yesterday.

John/Jaroslav, thanks for the effort in resolving my problem.
