c++ - Errors in iosfwd -

i´m not sure if plenty information, maintain getting error in iosfwd file, standard library.

i post code included it, don´t think did.

it keeps saying error 65 expected ; on multiple lines. lines similar to: typedef basic_fstream<char> fstream;.

i @ finish loss because sure file in standard library not have error , have semi-colon why expects one?

i using keil v5.
