Modified makefile to be more modular with icc and gcc options.
Modified portability.h with some stubs and some real portability code
Removed named variadic macros for unnamed variadic macros (c99 only supports unnamed)
Removed ', ## __VAR_ARGS__' in favor of ', __VAR_ARGS__' due to apparent bug in the intel compiler (on windows at least)
__ICC means the linux intel compiler, __ICL means the windows intel compiler
__INTEL_COMPILER is set by both
Removed some include files (for windows) that don't exist.
