>Description:
GCC doesn't recognize expressions of the form typeof()::type, and under certain circumstances it produces a request to submit a bug report. 
>How-To-Repeat:
If the attachment 'b.cc' is compiled with: 

 gcc -DA -c b.cc 

then this message: 
<quote>
b.cc: In function `int main()':
b.cc:10: `template<class _Category, class _Tp, class _Distance, class _Pointer,
   class _Reference> struct std::iterator' as declarator
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

If the attachment 'b.cc' is compiled with: 

 gcc -DB -c b.cc 

then this message: 

b.cc: In function `int main()':
b.cc:20: parse error before `=' token
b.cc:20: `it' undeclared (first use this function)
b.cc:20: (Each undeclared identifier is reported only once for each function it
   appears in.)
</quote>

is generated. In the -DB case the "using namespace std;" statement is removed.
