 Very interesting testcase for error reporting ICEs, but it needed some heavy
 cleanup.
 A first regression is the following:
 
 -------------------------------------------
 void func(void*, INVALID (*child_func)(INVALID));
 -------------------------------------------
 regr1.cpp:2: `child_func' was not declared in this scope
 regr1.cpp:2: `INVALID' was not declared in this scope
 regr1.cpp:2: type specifier omitted for parameter `
 Internal compiler error: Error reporting routines re-entered.
 Please submit a full bug report,
 
 But it's a regression on the (now closed) 3.2 branch only, 3.3 and 3.4 does
 not have this problem. So it can be ignored as already fixed.
 
 
 Then, we have this:
 
 -------------------------------------------
 typedef struct _foo foo;
 
 void bar(void) INVALID;
 
 struct _foo
 {};
 -------------------------------------------
 pr6682.cpp: In function `void bar()':
 pr6682.cpp:3: error: syntax error before `;' token
 pr6682.cpp:3: error: ISO C++ forbids declaration of `INVALID' with no type
 pr6682.cpp:6: error: declaration of `struct _foo' in `void bar()' which does
    not enclose `::'
 pr6682.cpp:6: internal compiler error: Segmentation fault
 Please submit a full bug report,
 
 which is a regression on the 3.3 branch only, with respect to 3.2 and
 previous. 3.4 does not have this problem.
 So I will keep this bug report open as a 3.3 regression, ice-on-illegal.
