Move some code under #ifdef guards. This works, but the main reason we
do it is that if we include these header files icc71 can't be used any
more on newer linux systems due to a stupid interaction with
/usr/include/linux.h that simply kicks out non-gcc versions (icc8
identifies itself as gcc, so isn't affected)...
