Hi,
from Intel icc 2015.3 to current 2016.0.109 there is problem with GCC 5.x headers.
Please see https://software.intel.com/en-us/forums/intel-c-compiler/topic/565143
Problem won't be probably fixed so fast, because is present for some time now, without fix or workaround.
Please do not create new Intel toolchain 2016.00 with GCC 5.2.0 headers, but with 4.9.3 instead.
Easyconfigs are in PR #1973 .
