[libgweather] Further Windows work

[Tor Lillqvist <tml src gnome org>]

commit c9df6469d1a38b6e3d71b1a271917ef7f2767fd7
Author: Tor Lillqvist <tml iki fi>
Date:   Fri May 29 17:07:52 2009 +0300

    Further Windows work
    
    Based on Fridrich Strba's work in the openSUSE build service's
    cross-compiled Windows package.
    
    Don't include gweather-win32.h in individual .c files, instead include
    it in weather-priv.h.
    
    Include <glib.h> in gweather-win32.c to get proper prototypes and
    G_OS_WIN32 definition.
    
    Add redirection also for GWEATHER_XML_LOCATION_DIR.
    
    Test _WIN32 in gweather-win32.h instead of G_OS_WIN32 as that is not
    necessarily defined if <glib.h> has not been included.
