As far as I can tell, PyArray_FromDims can be replaced with  
PyArray_SimpleNew -- they have the same function signature. If you  
want to be correct/avoid compiler warnings, you'd probably need to  
make sure to cast the second argument to (npy_intp*).

Likewise, PyArray_FromDimsAndData can be replaced with  
PyArray_SimpleNewFromData, with the same caveat about the cast.

So: it's a simple regexp to fix these two if you don't care about the  
casting, and a slightly more-involved one if you do. I'm not sure  
what's best here.
