-fno-default-inline and iostream.o

[colin at field dot medicine dot adelaide dot edu dot au]

With -fno-default-inline, iostream.h's

class _IO_ostream_withassign::_IO_ostream_withassign& operator=
	(_IO_ostream_withassign& rhs)
    { return operator= (static_cast<ostream&> (rhs)); }


is instantiated twice, once in the caller, and once in libstdc++.a(iostream.o), 
leading to multiple definitions at link-time.

The same occurs for several other methods.
