I ran this line on my windows/mingw setup.
I got:
d:\Python24\include
I haven't checked if this works for building.
(I normally  use  the forward slash format for everything  which would be 
/d/python24/include )

The config.log of my last build on windows (with my version of the python 
macros, not this new one) shows:
configure:21246: checking for python version
configure:21253: result: 2.4
configure:21265: checking for python platform
configure:21272: result: win32
configure:21279: checking for python script directory
configure:21287: result: /d/Python24/Lib/site-packages
configure:21296: checking for python extension module directory
configure:21304: result: /d/Python24/Lib/site-packages
configure:21321: checking for Python include path
configure:21344: result: /d/Python24/include

I am using MingW under windows.
(Never even tried cross-development from linux)

The important thing is to setup all dependencies right.
This means installing and building/installing a lot of libraries/tools.
install mingw
install msys
install python, wxpython  (standard windows binary versions, not mingw specific)
install python-win32 api (optional: for win32-named_pipes, only needed for 
fft-sink scope-sink)
build from source/install latest version of libtool
patch/buildfromsource/install fftw, cppunit
download boost-jam binary
buildfromsource/install boost

buildfromsource/install gnuradio-core
buildfromsource/install wxgui-win32
buildfromsource/install gr-aduio-windows

somehowinstall usrp stuff (no experience here)

use your favourite gnuradio python script

The only thing from the base-mingw/msys tools I upgraded is libtool.
