(In reply to comment #4)
The patch for 21275 failed to take care of C++ class members which "inherit" a 
dllimport attribute from the class type definition.

Here is a C++ testcase:

struct __attribute__ ((dllimport)) Foo
{
   static int bar (void);
};

typedef int(*foobar)(void);

foobar my_foobar = (foobar) &Foo::bar;

int my_bar()
{
  return my_foobar();
}

The code that marks Foo::bar as NON_ADDR_CONSTANT_P in winnt.c happens too 
late. 

I have a more invasive patch that fixes C and C++, replacing NON_ADDR_CONST_P 
with a target hook (dll-supporting targets are currently the only ones that set 
the tree_decl.non_addr_const_p flag).  I'll submit as soon as I can access a 
machine that will build and regtest Java on mingw.

Danny
