I am having difficulty with the old 3.02 version of Lattice.  I was
hoping that someone could either point out that I am making a mistake
or that there really is a major bug in the compiler.

The problem I am having is using a pointer to a function, for instance:

foo() {
 printf("Hi\n"); }


bar() {
 int (*funptr)();   /* I believe this is the correct declaration */

 funptr = foo;      /* this line compiles without error */
 funptr();          /* this line generates an ERROR so no quad file is made */
}


The error generated is:
  
15  The identifier preceding the ( function call operator was
    not implicitly or explicitly declared as a function.


I checked some old code I had written on a UNIX VAX that used function
pointers and it looked much like the above.  I don't understand why
this doesn't work and I can't find any way to force it to work.

If someone recognizes this as a known compiler bug; do you know if this
is corrected in version 3.03 or the beta test 3.04 version?

Thanks for the help,
