Actually, it's not ok. configure believes you are using gcc

which is clearly not correct. This may well screw the rest of configure 
and explains why you get these warnings:

 > icc: Command line warning: ignoring option '-Werror'; no argument 
required
 > icc: Command line warning: ignoring option '-W'; no argument required
 > icc: Command line warning: ignoring option '-W'; no argument required
 > icc: Command line warning: ignoring option '-p'; no argument required
 > icc: Command line remark: option '-MP' not supported

because the "-Werror" etc options are all specific to gcc.

What is causing make to fail? The lines you sent:

 > ../src/ftt.h(36): remark #193: zero used for undefined preprocessing
 > identifier
 >   #if (FTT_2D || FTT_2D3)

are only warnings (first time I hear of "remarks", that must be 
intel-specific) not errors. What are the last lines of the make output?

Anyway, it looks like configure does not detect icc properly. You should 
try to e-mail a question/bug report to the automake/autoconf mailing lists.

An alternative fix is not to use icc. Who installed MPI on your machine? 
Is it mpich? lam-mpi? You should try to install mpich or lam-mpi (I 
would recommend lam-mpi). This should work.
