Do you mean the ABI of the OpenCL API library (e.g. the abstraction over 
the various driver stacks) and the interoperability between those (for 
MSVC, I imagine) and StarPU compiled with GCC? Can I take this to mean 
that the OpenCL support of StarPU hasn't been tested on Windows?

OK;

I also tried building 0.4 on MaxOS X 10.6, and got the following 
configure error:

checking for lib... no
checking for pthread_create in -lpthread... no
configure: error: pthread_create unavailable

It looks like the use of -march with GCC is the problem. I don't think 
it is actually necessary, either.
