Hi,

(not really sure where to ask this, so I'll ask here)

In "The C++ Programming Language, 3rd Edition", it is stated that you
can use pointers with exception specifications. However, gcc-2.95.1
doesn't like this. For instance:

- cut here -------------------------------------------------------------
#include <iostream>

void myFunction(int) throw();

void (*f)(int) = myFunction;
void (*g)(int) throw() = myFunction;

int main()
{
    f(0);
    g(1);
    return 0;
}

void myFunction(int I) throw()
{
    cout << I << endl;
}
- cut here -------------------------------------------------------------

This should compile without any warnings or errors, and should never die
from an uncaught exception. However, when I try to compile:

  gxx -o test.exe test.cpp
  test.cpp:6: invalid exception specifications

So, my question: is this a feature that hasn't been implemented in GCC,
something that is not correct C++, or am I just doing something wrong
(like I usually am...).

Well, thanks for your help + time, and bye for now,
