I can answer to that question: the Intel Compiler (versions 11.0 and 11.1) is
tested by CGAL daily testsuite. You must make sure the following compilation
flags are used:
 -D_GLIBCXX_USE_C99_FP_MACROS_DYNAMIC=1 -fp-model strict -diag-disable 980

(Probably only -fp-model strict is important, and the other flags are there to
silent some warnings.)

*However*, the compilation flag -strict-ansi of the Intel Compiler is (not yet)
supported. I have added that setup (with -strict-ansi), and things are going
better and better. Probably Intel Compiler 11.1 with -strict-ansi will be
supported (or almost supported) by CGAL-3.7.

Can you give use an example of the error log you get?

I do not use the -strict-ansi flag, while I always set -fp-model strict. 

I have tried to build the libraries with 

cmake -DCMAKE_C_COMPILER=/opt/intel/Compiler/11.1/088/bin/intel64/icc -DCMAKE_CXX_COMPILER=/opt/intel/Compiler/11.1/088/bin/intel64/icpc -DWITH_examples=true

and then make. The libraries build (with some warnings that tell me there are duplicate libraries), but when I try to run the examples I always get "segmentation error". 

Now I am using the libraries built by gcc 4.5. 

When I try to compile the program that calls CGAL with icpc I get a list of error messages like this:

The program compiles and runs correctly when I use g++ 4.5.
