nothing surprising. Each new version of Intel software is orthogonal  
to all previous
versions, like in Lanczos chains.

of course it is (unless they changed the way blas and lapack routines  
are called).
Carlo Nervi told me a few days ago that he managed to have everything  
working
with ifort 11.1.056 and MKL 10.2.2.025.

if you want mkl to be recognized by configure, yes, configure.ac has  
to be
modified.

configure reports what your operating system says. If it works, it is  
fine.
