I am trying to configure Open MPI using CMake 2.8.8 and Visual Studio 2005 in 32 bit mode, with Intel Fortran.  The machine is a 64 bit machine running Windows XP 64 bit, and VS has 64 bit support.
Configure works fine without f77 bindings, but as soon as I add this option, I get the error:

Fortran compiler ifort.exe can't compile a simple fortran program.

Configuring incomplete, errors occurred!
I am using all default options, except that I have specified a cmake_build_type of release.  Both the c and cxx compilers appear to be pointing to the 64 bit versions, but changing these to the 32 bit versions does not seem to matter.  
If I attempt to compile testFortranCompiler from a command prompt it compiles without any difficulties (ifort testFortranCompiler.f, with no other flags). 
Any ideas which options I am missing to get this to work?
