Marcus,
        I'm puzzled. Before even taking SWIG into the picture, how would 
the C function know the length of the array you're passing? Is it some kind 
of global variable, does the array use some kind of terminator, or (more 
likely) is the function actually declared as
    int calc( double*, int size ) ?
In the first case, you can simply use the global variable; in the second 
case, you'll have to use PyList_Size and build the array, including the 
terminator; in the third case (which I do hope is the one you're using) you 
can write a typemap for both arguments at once (see 
http://www.swig.org/Doc1.3/Typemaps.html#n40 for details).

Hope this helps,
                Luigi
