Fails to parse any struct/class with an __attribute__ attached to it

NOTE: I reported this issue as QTCREATORBUG-994 before, and it was stated to be fixed in 2.0.0-beta. However, I tried the newly released 2.0.0-beta today and the issue is still there. Therefore I would like to reopen this bug report. Since I haven't found a button to reopen the existing QTCREATORBUG-994 entry, I had to clone it here. The text of the original entry follows.

Here's an example struct declaration Qt Creator has problems with:

struct MyStruct
{
char a;
char b;
} _attribute_((packed));

Qt Creator fails to parse that struct. It won't autocomplete its fields, it won't go to its declaration, and so on. It just doesn't exist for it.

The _attribute_ mechanism is a standard gcc feature which quite widely used. It's the only way to declare structure packing, for example. It would be nice if Qt Creator would parse such declarations correctly.
