- new flag "-utf16" to enable "utf16" conversion [Bug #1075229].

- new logic to automatically enable or disable "utf16" conversion :
    no locale, locale=="C" or locale=="POSIX" implies utf16=off
    else  utf16=on
    uses "-utf16" or "-no-utf16" to change this behaviour.

    - remove stuff for GUID_SECTION and GUID_SECT in include_windows/basetyps.h
      and include_windows/initguid.h
