  src/contrib/gcc.295 - Imported sources
  Update of /home/ncvs/src/contrib/gcc.295
  In directory freefall.freebsd.org:/c/tmp/cvs-serv65307
  
  Log Message:
  Import the setjump/longjump exception handling fixes from GCC 2.95.3.test3
  that were removed from GCC 2.95.3.test4 and the subsequent release due
  to problems on HP-UX.  However, they work just fine on all the BSD's.
  
  W/o these patches the following program segmentation faults if compiled
  with -O2 (but not -Os or -O or -O0):
  
  #include <stdio.h>
  
  class A {
  public:
    A() { printf("c'tor A\n"); }
    ~A(){ printf("d'tor A\n"); }
  };
  
  class foo : public A {
  public:
    foo()  { printf("C'tor foo\n"); throw 8; }
    ~foo() { printf("D'tor foo\n"); }
  };
  
  int main(){
    try { foo fii; }
    catch (int){ printf("catch ...\n"); }
    return 0;
  }
