make check results of sparse\svds.m and ATLAS

[Tatsuro MATSUOKA]

Hello

I have sometimes encountered the following results for sparse\svds.m test in 
make check.

The element seems to be shifted by one

 [u2,s2,v2,flag] = svds(a,k,0);
 s2 = diag(s2);
 assert(flag,!1);
 assert(s(k:-1:1), s2, 1e-10); 
!!!!! test failed

This error depend on the ATLAS libraries used. 

The ATLAS libraries are produced on cygwin and I used them for octave building 
on MinGW + Msys. 

If I use reference blas this error does not occuer.
I at the moment carried out systematic experiments so that I do not know why 
this happens at the
moment.  But I report here as a reference. 

If there are suggestion, they are welcome!!

Regards

Tatsuro
