Because we (at the Belgian Institute of Space Aeronmy) try
to use the Intel Compilers as much as possible, and as I also
compiled the dependencies (fftw3, arpack, glpk, qhull, qrupdate,
hdf5, metis, suitesparse-metis) with those compilers, I expect
the upgrade to work the same way. Of course, if there is no
solution ... then a "fallback" to the GNU compilers is the
best way to get it working.

Vincent.
