The message about CPU_ENABLE_SSE exists, however it does not say about
a signal:

If you use icc on a Pentium 4 you may have to use 'options CPU_ENABLE_SSE'
(depending on the OS version, if in doubt try if it works) in your kernel
config (have a look at http://www.FreeBSD.org/handbook/ if you do not know
how to do this), else icc will hang forever."

The __gnuc_va_list errors could be fixed by adding "-D__gnuc_va_list=va_list"
to /usr/local/intel_cc_80/bin/icc.cfg and /usr/local/intel_cc_80/bin/icpc.cfg,
but how to fix __mbstate_t error I do not know.
