>Description:
Five tests in g++.old-deja/g++.pt (instantiate[46].C and
repo[124].C) fail because some templates are not
instantiated with -frepo.  This affects powerpc64-linux,
both cross compilers and native 64-bit compilers, for
mainline, 3.3-branch, and 3.2-branch.

Here's what happens with test repo1.C:

  % g++ -c -frepo repo1.C
  % g++ -frepo repo1.o
  repo1.o: In function `.main':
  repo1.o(.text+0x18): undefined reference to `.void g<int>(int)'
  collect2: ld returned 1 exit status

That test:

template <class T> struct A {
  virtual ~A () { }
};
template <class T> void g (T t) { }
template class A<int>;
int main ()
{
  g (42);
}
