Perhaps you are using the wrong cross-compiler for this canandian cross 
build?  You can check by adding -v to the above compiler command.

When building a canadian cross, you must use a cross compiler of the 
same gcc version.  In this case, the i686-pc-mingw32-gcc must be built 
from the same gcc-4.0-branch sources you are using for the canadian 
cross build.

You should consider using --prefix options so that each gcc version gets 
installed in a different place.  This will help avoid confusion about 
gcc versions.
