Fix a build issue under Debian Kfreebsd & Hurd

[Sylvestre Ledru]

Hello,

The attached patch fixes the build of subsurface under Debian Kfreebsd &
HURD.

Otherwise, it fails with:

    CC windows.c
gcc -Wall -Wno-pointer-sign -g -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -DGSEAL_ENABLE -I/usr/include/libxml2 -pthread -I/usr/include/gtk-2.0 -I/usr/lib/x86_64-kfreebsd-gnu/gtk-2.0/include -I/usr/include/atk-1.0 -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pango-1.0 -I/usr/include/gio-unix-2.0/ -I/usr/include/glib-2.0 -I/usr/lib/x86_64-kfreebsd-gnu/glib-2.0/include -I/usr/include/pixman-1 -I/usr/include/freetype2 -I/usr/include/libpng12   -I/usr/include/glib-2.0 -I/usr/lib/x86_64-kfreebsd-gnu/glib-2.0/include   -I/usr/include/libxml2 -DXSLT='".\\xslt"'   -pthread -I/usr/include/libsoup-2.4 -I/usr/include/libxml2 -I/usr/include/glib-2.0 -I/usr/lib/x86_64-kfreebsd-gnu/glib-2.0/include     -MD -MF .dep/windows.o.dep -c -o windows.o windows.c
windows.c:5:21: fatal error: windows.h: No such file or directory

Thanks,
