Ok, I tried this:

I applied the following changes to ov.h and ov-base.h
--- ov.h        2007-01-30 17:28:49.276678400 +0100

and run mkoctfile, but end up with a different error message

LINK : fatal error LNK1104: cannot open file 'lapack.lib'

Searching the installation tree yields only the following .lib files:
cruft.lib
octave.lib
octave_fixed.lib
octinterp.lib

So I guess not only lapack.lib is missing but probably also the other libaries 
listed as arguments to cc-msvc (fftw3, blas, hdf5, zlib, f2c)

Extrapolating a bit I guess that the header file fftw.h is also missing, since 
oct-fftw.h contains a #include <fftw3.h> statement, although I have not yet 
tried compiling an oct file containing calls to fft().
