Add a header variadic-macro.h which defines the CALL_MACRO_FOR_EACH marco.

This macro can be used as follows:
  #define TEST(x)
  CALL_MACRO_FOR_EACH(TEST, a, b, c, d)

This will expand to
  TEST(a) TEST(b) TEST(c) TEST(d)

The nice thing is that CALL_MACRO_FOR_EACH is a variadic macro, thus the
number of arguments can vary (although it has an upper limit - in this
implementation 32 arguments).
