POC:

int f2 ( int x [ strcmp ( ) ] , int b ) { return c - b ;
 }
 int ( * f1 ( int a , enum E2 { E = -2 , F , G , H }
 b ) ) ( int c , int b ) { if ( a != b ) return f2 ;
 return 0 ;
 }
 int main ( ) { int ( * ( * p ) ( int a , int b ) ) ( int c , int d ) = f1 ;
 return ( * ( * p ) ( 0 , 2 ) ) ( 2 , 2 ) ;
 }
