[Bug c++/38759] New: Incorrect warning/error when compiling with a typedef'ed ptr return type

[gnu at bluedreamer dot com]

When a pointer to type is typedef'ed to a new type gcc incorrectly warns about
const modifier if new typedef is used in function return type.

gcc info:
dluadrianc:/home/adrianc> gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.3.1/configure --prefix=/usr --enable-languages=c,c++

Command line:g++ -save-temps -Wall -ansi -Wextra -pedantic -Werror const.cc
Error message:

class Foo { };

const Foo *func1()
{
   return 0;
}

typedef Foo* Bar;

const Bar func2()
{
   return 0;
}

int main(int , char *[])
{
   func1();
   func2();

   return 0;
}
