The following example illustrates the rules for redefinition, tokenization, macro
replacement, and replacement list reexamination:
#define x 3
#define q x
#define f(i) f(q + (i->m))
#define b b + c
#undef x
#define x 5
#define z(a) a
#define g f
#define j )
#define d +
#define e +
#define r(a, b) (a)(b)
#define s(a, b) a(b)
#define y g(y)
r(f, g)
s(f, q)
g(36j
#undef q
#define q d
f(b + c)
f(y)
