[Bug c++/19244] New: Typedef of anonymous class incorrectly handled in member function definition

[austern at apple dot com]

gcc 4.0 incorrectly rejects the following valid code:
typedef struct { void f(); } f;
void f::f() { }

It treats f::f as referring to a constructor, and then gets confused because this isn't the right syntax for 
a constructor definition.  However (12.1/3), "a typedef-name that names a class shall not be used as 
the identifier in the declarator for a constructor declaration."

Note that this only happens for an anonymous class.  If I instead write
typedef struct e { void f(); } f;
then this compiles without error.

This is a regression.  3.3 handles this correctly.
