[Numpy-discussion] Building Numpy under Python 1.6, Windows

I have recently upgraded to Python 1.6 (final). Now I can't figure out how 
to build Numpy with lapack_lite under windows. There is not a makefile for 
lapack_lite for MSVC and the instructions in README don't really help. All 
that setup.py will do is complain that lapack_lite is not installed.

Specifically, are there specific compiler flags that I need to use to 
compile lapack lite? Should I just emulate the unix version and do

cl -c *.c
lib -out:blas.lib blas_lite.obj
lib -out:lapack.lib dlapack_lite.obj f2c_lite.obj zlapack_lite.obj

I tried doing this, but when I try to run the NumTut examples, I get the 
following error:

FWIW, I am using the versions from 
:pserver:anonymous at cvs.numpy.sourceforge.net:/cvsroot/numpy, module 
Numerical, checked out as of Sept. 14. I didn't see any tags defined in the 
repository corresponding to release 16.x. Did I miss something? Should the 
releases not be getting tagged in the CVS repository?

Thanks for any pointers,
