simplified egcs 1.1 DJGPP eh test case

[Mark E.]

This test case is based on a previous case by Andris Pavenis. This 
affects DJGPP (i386-pc-msdosdjgpp).

In the test case below, throwing an 'empty' class results in an abort. 
But when a do-nothing constructor and destructor are added to the 
class, the exception is properly catched.

#include <iostream>

// Test example for exceptions problem with DJGPP port of egcs-1.1

// If the next line is uncommented, the exception is catched;
// otherwise, throwing the exception causes an abort in egcs's copy_reg

//#define USERDEF_XTORS

class xx {
#ifdef USERDEF_XTORS
public:
  xx() {}
  ~xx() {}
#endif
};

void x2 (void)
{
  xx a;
  throw(a);
}

int main (void)
{
  try { x2(); } catch (xx& w) { cout << "catched from x2()\n"; }
  cout << "----------------\n";
  return 0;
}
