win32 warning - g_win32_get_system_data_dirs

[Michael Cronenworth <mike cchtml com>]

I have just added Win32 GTK development to my existing Linux development 
experience, and I am getting a warning when using GTK 2.14.7 and MinGW:

C:/msys/1.0/include/glib-2.0/glib/gutils.h: In function 
`g_win32_get_system_data_dirs':
C:/msys/1.0/include/glib-2.0/glib/gutils.h:143: warning: ISO C forbids 
conversion of function pointer to object pointer type

Bug that caused this: http://bugzilla.gnome.org/show_bug.cgi?id=173098

My ugly patch:

It probably needs work, but this removes the warning and should keep the 
same functionality. Anyone have any recommendations: File a new bug? 
Open the old bug?
