>Description:
The following code has always been rejected by GCC:
-----------------------------------
struct Foo
{
static int func(void);
enum { value = sizeof(func()) };
};
-----------------------------------
gccbug1.cpp:5: error: invalid use of undefined type `struct Foo'
gccbug1.cpp:2: error: forward declaration of `struct Foo'
gccbug1.cpp:5: error: enumerator value for `value' not integer constant
Notice that it's possible to make the code compile simply
by qualifying the function name: sizeof(Foo::func()).
>How-To-Repeat:
Compile the above snippet
>Fix:
Qualify the function name
