The following does not compile with -O0, but does with -O2. It used to
work well on gcc-3.2 and gcc-3.1

  $  cat t.cc
  template <class T> inline void Foo(T) __attribute__((always_inline));
  template <class T> inline void Foo(T) {}
  int main() 
  {
     int i; 
     Foo(i); 
  }
  $ $gcc34/bin/g++ -c t.cc
  t.cc: In function `int main()':
  t.cc:2: sorry, unimplemented: inlining failed in call to 'void Foo(T) 
[with T = int]': function body not available
  t.cc:6: sorry, unimplemented: called from here

When compiled with -O, it works OK. When the same is done without 
templates it works OK:

  $ cat t2.cc
  inline void Foo(int) __attribute__((always_inline));
  inline void Foo(int) {}
  int main()
  {
    int i;
    Foo(i);
  }

This is inconsistent.

  $ $gcc34/bin/g++ -v
