The non-inline specialization of an inline member function of a template class is not being treated as 
inline when using precompiled headers.

For example, consider

  test.H:
    template <class T> class simple_class {
      public:
        inline void testfn (T);
    };

  test.C:
    #include "test.H"

    template <> void simple_class<int>::testfn (int) {}

    int main (int argc, char *argv[])
    {
      simple_class<int> sc1;
      sc1.testfn (5);
    }

When compiled without precompiled headers, the function appears a simple global function:

        .global _ZN12simple_classIiE6testfnEi

But when test.H is first compiled (with "g++ test.H") into a PCH, and then test.C is compiled, the 
function appears as a weak symbol in a COMDAT section, implying that g++ is considering the 
specialization "inline" even though it isn't marked as such.

        .section        .text._ZN12simple_classIiE6testfnEi,"axG",%
progbits,_ZN12simple_classIiE6testfnEi,comdat
        .align  2
        .weak   _ZN12simple_classIiE6testfnEi
        .type   _ZN12simple_classIiE6testfnEi, %function
