Great, it's working. Here are the steps i've followed.

[1] The error was because of a bad use of sqrt function in wxproj.cpp.

The following correction made the trick :
line 468 : 
    len = (long)sqrt(vx * vx + vy * vy);
becomes :
    len = (long)sqrt((float)vx * vx + vy * vy);

[2] Downloaded and build proj 4.4.6

[3] Adapted path to have nmake.exe and lib.exe in the path (from
Platform sdk)

[4] Removed ctl3d32.lib from the setup.py

[5] Downloaded and build gdal 1.3.1

[6] Missing for building gdal, I've created msvcprt.lib
(http://libsh.org/win32/build.html ) :
	echo LIBRARY msvcp71.dll > msvcprt.def
	echo EXPORTS >> msvcprt.def
	lib -dump /exports msvcp71.dll | sed -nf exports.sed >> msvcprt.def
	lib /def:msvcprt.def /machine:x86

[7] Problem of MSVCtoolkit in C:\Program Files\Microsoft Platform SDK
\Include\atlPSDK\Include\atl\atlbase.h. The include of atlthunk.lib is
not possible because not given with the environment (same with
VisualStudio Express 2005). You need to remove the following line :
293 : #pragma comment(lib, "atlthunk.lib")

See :

! if you have the problem, clean the build system before retrying

[8] added gdal\gcore  to the list of includes :
  gdal_inc = [os.path.join(gdal_prefix, 'alg'),
                os.path.join(gdal_prefix, 'ogr'),
                os.path.join(gdal_prefix, 'port'),
                os.path.join(gdal_prefix, 'gcore'),
                os.path.join(gdal_prefix, 'core')]

Then:

python setup.py build
python setup.py install

worked fine... now i need to test it.
