[Bug c++/34749] New: Incorrect warning when applying dllimport to friend function

["sldev327 at softmagi dot com" <gcc-bugzilla@gcc.gnu.org>]

I was playing with some code and got a warning about dllimport in some
headers.  I looked around a bit and came up with this test case.

The warning seems to imply that dllimport is ignored on bar(), but looking at
the output the call to bar() is indeed mangled with __imp prefix.

I'm using MinGW g++ 4.2.1-dw2.

## begin df.cpp
__attribute__((dllimport)) int bar();

class Foo
{
private:
    int foo();
    friend __attribute__((dllimport)) int bar();
};

int Foo::foo()
{
    return bar();
}
## end df.cpp

D:> g++ -S df.cpp
df.cpp:7: warning: 'int bar()' redeclared without dllimport attribute:
previous dllimport ignored

D:> g++ -v
