| Taken from https://stackoverflow.com/questions/27582001/how-to-use-128-bit-integers-in-cython | |
| Basically, we make cython believe we will use 64 bit int to generate the .c file, | |
| but by using a C header we will, in fact, define a 128 bit int (the definition | |
| in the .h file does not match what we put into the pyx file). | |
| Once Cython has generated the .c file, we can compile it with GCC without further trouble, | |
| as GCC does support 128 bit ints |
