I see.  AFAIK, WEAK symbols are now supported and used on HP.  Maybe
they just show up as `t' symbols?  Or maybe it is indeed some new bug?

So, summarizing to the list the discussion we've had in private,
given:

h.h:
struct A {
  A() {}
  virtual void f();
};

x.cc:
#include "h.h"
void A::f() {}

y.cc:
#include "h.h"
A a;

if you compile x.cc and y.cc without optimization, linking fails
because the constructor is defined as local in x.o and not defined at
all in y.  Is that correct?
