Your compiler gets the wrong header files for glib-2.0.

configure uses pkg-config to get the correct compiler options.
For your cross compilations, it calls x86_64-w64-mingw32-pkg-config.
Here is an example from my build machine:

$ x86_64-w64-mingw32-pkg-config --cflags glib-2.0
-mms-bitfields -I/usr/x86_64-w64-mingw32/include/glib-2.0
-I/usr/x86_64-w64-mingw32/lib/glib-2.0/include

So the header files are in /usr/x86_64-w64-mingw32/include/glib-2.0,
not in /usr/include/glib-2.0 (those are the header files for native
compilation).

Did you install glib-2.0 for cross compilation? I use the bundle from
ftp.gnome.org/pub/gnome/binaries/win64/gtk+/2.22/gtk+-bundle_2.22.1-20101=
229_win64.zip.
