[C++-sig] errors while setting arguments description for the method

[Gennadiy Rozental]

I've got specification like this:

    class_<Foo,FooSP>( "Foo", "Foo descr" )
     .def( "__init__", bp::make_constructor( &make_foo ), 
           bp::args( "self", "str" ), 
           "Constructor based on string representation.\n" )
...

I am getting compilation error below from VC9.0. Error disappears if I avoid
bp::args( "self", "str" ) part.

Please advise,

Gennadiy
