problem about cross compiling win32 program under linux

[Roy Chang <acm zrl gmail com>]

I tend to compile win32 gtk program under linux using mingw like this:

i486-mingw32-gcc  `pkg-config --libs --cflags gtk+-2.0` -Isoftware/win_gtk_dev/zlib-dev_1.2.4-2_win32/include -Lsoftware/win_gtk_dev/zlib-dev_1.2.4-2_win32/lib -lz -Isoftware/win_gtk_dev/gettext-runtime-dev-0.17-1/include -Lsoftware/win_gtk_dev/gettext-runtime-dev-0.17-1/lib hello.c -o hello.exe

and the pkg-config result is:

-mms-bitfields -Isoftware/win_gtk_dev/glib-dev_2.24.0-2_win32/include/glib-2.0 -Isoftware/win_gtk_dev/glib-dev_2.24.0-2_win32/lib/glib-2.0/include -Isoftware/win_gtk_dev/gtk+-dev_2.20.0-1_win32/include/gtk-2.0 -Isoftware/win_gtk_dev/gtk+-dev_2.20.0-1_win32/lib/gtk-2.0/include -Isoftware/win_gtk_dev/atk-dev_1.30.0-1_win32/include/atk-1.0 -Isoftware/win_gtk_dev/pango-dev_1.28.0-1_win32/include/pango-1.0 -Isoftware/win_gtk_dev/cairo-dev_1.8.10-3_win32/include/cairo -Isoftware/win_gtk_dev/freetype-dev_2.3.12-1_win32/include/freetype2 -Isoftware/win_gtk_dev/freetype-dev_2.3.12-1_win32/include -Isoftware/win_gtk_dev/libpng-dev_1.4.0-1_win32/include/libpng14 -Isoftware/win_gtk_dev/fontconfig-dev_2.8.0-2_win32/include  -Lsoftware/win_gtk_dev/glib-dev_2.24.0-2_win32/lib -Lsoftware/win_gtk_dev/gtk+-dev_2.20.0-1_win32/lib -Lsoftware/win_gtk_dev/atk-dev_1.30.0-1_win32/lib -Lsoftware/win_gtk_dev/pango-dev_1.28.0-1_win32/lib -Lsoftware/win_gtk_dev/cairo-dev_1.8.10-3_win32/lib -lgtk-win32-2.0 -lgdk-win32-2.0 -latk-1.0 -lgio-2.0 -lgdk_pixbuf-2.0 -lpangowin32-1.0 -lgdi32 -lpangocairo-1.0 -lpango-1.0 -lcairo -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lglib-2.0 -lintl

but the gcc got errors like this:

anyone know what's the matter? thank you :)
