Thank you!

I ran into the following issues with scipy 0.9.0b1 on Windows when 
building with msvc 9 and intel 11.1 compilers. Numpy is version 1.5.1, 
linked against MKL.

1) after patching some source files and setup scripts (see msvc9.diff 
attachment), "python setup.py bdist_winist" succeeds on 32- and 64-bit 
Python 2.6, 2.7, and 3.1. The Visual C compiler reproducibly crashes 
while compiling scipy\special\cephes\ndtr.c. Running the build command 
again (without cleaning the build directory) seems to work.


2) the build process fails on Python 3.2b1 with the following errors:

scipy\sparse\sparsetools\csr_wrap.cxx(2451) : error C3861: 
'PyCObject_Import': identifier not found
scipy\sparse\sparsetools\csr_wrap.cxx(2521) : error C3861: 
'PyCObject_FromVoidPtr': identifier not found
scipy\sparse\sparsetools\csr_wrap.cxx(2544) : error C3861: 
'PyCObject_AsVoidPtr': identifier not found


3) 32-bit Python 2.6 is the only platform where scipy.test() finishes; 
albeit with 32 failures. Besides the Correlate complex192 and TestODR 
errors (http://projects.scipy.org/scipy/ticket/678) I get

FAIL: Real-valued Bessel domains
----------------------------------------------------------------------
Traceback (most recent call last):
   File 
"X:\Python26\lib\site-packages\scipy\special\tests\test_basic.py", line 
1704, in test_ticket_854
     assert_(not isnan(special.airye(-1)[2:4]).any(), special.airye(-1))
   File "X:\Python26\lib\site-packages\numpy\testing\utils.py", line 34, 
in assert_
     raise AssertionError(msg)
AssertionError: (nan, nan, nan, nan)


4) scipy.test() on Python 2.7 and 3.1 crashes as reported in ticket 
#1210 <http://projects.scipy.org/scipy/ticket/1210>


5) On 64 bit platforms, scipy.test() quits at the following test

test_interpnd.TestCloughTocher2DInterpolator.test_dense ... QH6084 qhull 
internal error (qh_meminit): sizeof(void*) 8 > sizeof(ptr_intT) 4. 
Change ptr_intT in mem.h to 'long long'
