Commas in macro arguments

[Claus Tondering]

Suppose I have the following macro definition:

#define call(a,b)	a(b)

I can use that to call a function with one argument. How can I use
it to call a function with two arguments? In other words: How do I
pass a string containing a comma as the second argument to the macro?
Can it be done, or is it impossible?
