Hello Ralf,

looks good. Just some minor issues:

1) I was unable to build from scipy-0.10.0b2.zip: "error: 
src\fblaswrap.f: No such file or directory". The git branch is OK.

2) Can the file japanese_utf8.txt in scipy\io\matlab\tests\data somehow 
be marked as binary on github? It is automatically converted to Windows 
line endings such that test_mio.test_load fails.

3) Building with Intel C compiler fails on Windows due to a bug in 
Cython 0.15, which has recently been fixed 
The following files are affected:


4) FAIL: test_datatypes.test_uint64_max
Traceback (most recent call last):
   File "X:\Python27\lib\site-packages\nose\case.py", line 197, in runTest
line 57, in test_uint64_max
     assert_true(x[1] > (2**63))
AssertionError: False is not true

This is due to the 32 bit visual C compiler using signed int64 when 
converting between uint64 to double.  Anyway, it seems unreliable to me 
to cast back and forth between uint64 and double types for large numbers 
because of potential overflow and precision loss.

5) Two known failures in test_arpack.test_complex_nonsymmetric_modes and 
Ticket 1515 <http://projects.scipy.org/scipy/ticket/1515>.
