I have built a mingw32 binary of the 3.0.2 release and find the 
following make check failures:

1) the one in rand.cc -> we know about the typo. fixed.

  f = @(x) a + x;

Also known and not yet dealt with (specific bug on mingw32)

but got
[-0.3333+0i,0+0.14i;0.3333+0i,0-0.14i]

Now this one, I don't consider a bug, rather a stange test.
Why would I expect that -i has a real part of -0 (mind the sign!)?
Doing
   real(-i)
yields
   ans = 0
as expected, and
   sprintf("%f", real(-i))
yields
   0.00000
also as expected.

I don't get the point here. imag(-1) is expected to be 0 (without the 
sign) but not vice versa.
Could the author of the test explain, why the negative sign is expected 
here?

}

This one, Micheal reported to have been fixed in newer sources, so I 
don't bother with it, right?


So the build looks good.
I have a necessary patch for pkg.m, but I'll post it seperately.
