Compiling with icc-2018.1.163-GCC-6.4.0-2.28 clashes with system libraries

[stevenvdb]

When compiling software with icc from icc/2018.1.163-GCC-6.4.0-2.28, there are errors because it is not compatible with newer versions of for example the system math headers. To work around this, the following lines can be added to the top of EBROOT_ICC/compilers_and_libraries_2018.1.163/linux/compiler/include/math.h:

#define __PURE_INTEL_C99_HEADERS__

#ifndef M_PI
#define M_PI 3.14159265358979323846
#endif
#ifndef M_PI_2
#define M_PI_2 1.57079632679489661923
#endif
#ifndef M_PI_4
#define M_PI_4 0.785398163397448309616
#endif
#ifndef M_2_PI
#define M_2_PI 0.636619772367581343076
#endif
#ifndef M_LOG2E
#define M_LOG2E 1.44269504088896340736
#endif

For now this is done manually afterwards, not using EasyBuild.
