I believe this refers to std::fpos<>::_Stz from <iosfwd>. This appears 
to refer to a specialization on a const type, which in turn makes me 
think of Borland's bug of not dropping the top level const qualification 
in argument deduction.

What I do not know is what is triggering this and whether in this case 
the usual workaround is applicable, which is to specify explicitly the 
relevant function's template arguments.
