This one boils down to:

    typedef struct B A;
    struct A { };

which although valid C is invalid C++ since FILE was declared at

  /files/pfeifer/OBJ-0317-09:57/gcc/include/floatingpoint.h:52

to be a synonym for 'struct __FILE' and at 

  /usr/include/stdio_impl.h:39

as the name a class named 'FILE'.

/usr/include/stdio_impl.h is solaris system file; however I don't know
where /files/pfeifer/OBJ-0317-09:57/gcc/include/floatingpoint.h is
coming from.  Gerald, could you enlighten us? 

A fix would be to change

   typedef struct __FILE FILE;

to

  typedef struct FILE FILE;

when #includeing /files/pfeifer/OBJ-0317-09:57/gcc/include/floatingpoint.h
as a C++ file.
