Parsing of explicit template specializations loses attribute
directive if the attributes are declared immediately after the the class-key
rather than at the curly bracket end of class definition.
eg:
==================================================
// attrib11.C
template <class intT> struct Bar{};
template<> struct Bar<int>
{
char c;
int i;
} __attribute__ ((packed)); // is packed.
template<> struct __attribute__ ((packed)) Bar<short>
{
char c;
int i;
}; // is _not_ packed
Bar<int> iBar;
Bar<short> sBar;
char test[sizeof iBar == sizeof sBar ? 1 : -1];
// end attrib11.C
==================================================
This has significance to dll[im/ex]port attribute, since
the second form (with __attribute__(()) replaced by __declspec())
is the one accepted by the native w32 compiler.
