Which version of MPICH2 are you using?  mpich2-1.5a1?  Are you actually cross-compiling or is this just a misleading message from a non-cross build?

If you are using 1.5a1, there's a reasonable chance that we broke cross-compilation and/or some Fortran integer size detection somehow with the new build system that was introduced in 1.5a1.
