FILE_NAME_INFO struct in 'glib/gmessages.c'

[John Emmas <john creativepost co uk>]

I just tried building Glib from git master (non-meson build at the moment).

In 'config.h.win32.in' it looks like the value of _WIN32_WINNT got 
increased to 0x601.  This means that when building 'glib/gmessages.c' 
the struct _FILE_NAME_INFO is no longer defined. However... it's still 
getting referenced in the function 'win32_is_pipe_tty()'

Similarly... HAVE_IF_NAMETOINDEX is defined to '1' in a couple of places 
- which means that in 'gio/gsocket.c' the function 'if_nametoindex()' is 
NOT defined.  But again it gets called in a couple of places.  It looks 
like the Glib definition was maybe intended to support older versions of 
MSVC (I'm using VC-8).  So does this mean that VC-8 will be getting 
dropped soon?  Thanks,

John
