If you consider the following PHP+C polyglot snippet, there is a problem regarding class property access in the printf call:

#define class struct
#define function 

class Point {
#define public int
    public $x;
    public $y;
};

// M4_INT
function main()
{
    // $p = new Point ...
    printf("%d", $p->x);  // PHP expects $p->x, but C expects $p->$x
    return 0;
}

My question is, how to resolve this in a neat manner? Possible solutions:

1. Remove all $ via sed before compiling with gcc
2. Define public $x as int x using #if __PHP__
3. Edit: Use getters, maybe? (works in C by passing self as first argument with function pointers)

Trying to define dollar sign as empty space does not work:

#define $ 

Any other ideas? I am also considering using m4 in the C Makefile. Thank you. :)
