Blender Build Error on Windows XP

Hi,

I’m building Blender from source on Windows XP 32bit and everytime I try to run the scons.py it crashes at :

COMPILING ==> FLUID_3D.cpp

it says it cannot find the file ‘omp.h’ which I presume is a header file. Is this a known problem and if so how should I fix it?

Thanks
Tom
