Maybe somebody already solved similar problems?

Or maybe not ?
The failing script can be reduced to: 
use strict;
use warnings;

use Inline CPP => <<'CPP';

#include <sstream>

CPP

1;

[download]
which (I think) still produces the same errors.

This would suggest that there's some fundamental incompatibility between perl.h and the sstream header with mingw-w64 compilers.
But it's not clear to me just what that incompatibility is. (We might need someone with some C++ insights to chime in.)

Do you really need to include sstream ?

UPDATE: For those interested, the original post has been cross-posted to stackoverflow.
