Proposed solution

Bug fix:
In Function MSVCRT_fputc from dlls/msvcrt/file.c, if there are no errors, the
same character that has been written should be returned, but the value should
be converted to an 'unsigned char' before will be returned. Otherwise e.g. if
input character = 0xffffffff, the returned value will not equal to 0xff, we
will 
get EOF instead.

Small improvement:
In my opinion, the function MSVCRT_fputc flushes a buffer when get '\n' and it
is OK, but when the file is opened in binary mode this behaviour is unnecessary
and decrease efficiency.
