cuda mex file

Hi,
please can anybody tell me how can I compile a cuda mex file with visual studio 2010 windows 7 64bit matlab r2011b cuda 4.0.
Since I have also Visual studio 2008 installe I tried to use this configuration http://forums.nvidia…a/gpu/index.htm
but I always obtain this error:
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\BIN/…/…/VC/\INCLUDE\ crtdefs.h(490): error: invalid redeclaration of type name “size_t”

Any ideas?
Thanks in advance.
