I'm trying to learn how to throw classes, but something weird is going
on.  Here's the code, which is right out of a book I am reading:

#include <iostream.h>

class B {};

void main(void)
{
   B b();
   try
   {
      throw b;
   }
   catch(B c)
   {
      cout << "Caught!" << endl;
   }
}

Compiling works just fine.  But, ld returns an error:
undefined reference to 'b(void)'

I've not been able to figure out if DJGPP can't throw classes or what.

Thanks for you help,
Chad
