Cross compiler problem (xgcc does not find standard includes)

Hi,
i have this problem:
i configured by
../egcs-19990629/configure --target=i686-pc-mingw32

and built on linux x86 with

make CFLAGS='-O3 -fomit-frame-pointer' LIBCFLAGS='-O3 -fomit-frame-pointer' LIBCXXFLAGS='-O3 -fno-implicit-templates -fomit-frame-pointer' cross

and get this:
/home/kahlert/LOCAL/obj/gcc/xgcc -B/home/kahlert/LOCAL/obj/gcc/
                 -B/usr/local/i686-pc-mingw32/bin/ -c -DHAVE_CONFIG_H -O3
		 -fomit-frame-pointer -I. -I../../../egcs-19990629/libiberty/../include

I assume the headers should be the one for the host. So they should be found in the standard 
directories.

What do i make wrong?

Thanks for every hint,
Martin.
