NO! It is not possible to do in C! (Im pretty sure you cant do this
in ANSI C either). 

What you can do is pass the address of a function to another function
and call that function:

     int runAfunct( myfunct )
       int (*myfunct)();
     {
        (*myfunct)();
     }

     int someFunct()
     {
       return 10;
     }

     main()
     {
       int  i;

       i = runAfunct( someFunct );
       printf( "%d\n", i );

       exit( 0 );
     }

 
Hope this helps!!!
