The definition of G_PI is IMO a bit misguided.  It has 50
decimal digits, but I cannot imagine how this excessive
precision could be used (except putting it into a string and
parsing that) because long double literals need an `l'
suffix:

#define MY_LONG_PI 3.1415926535897932384626433832795028841971693993751l
                                                                      ^here
