Hello,
When disabling standard headers inclusion, it is impossible to use GCC
intrinsics:

$ ./release/usr/local/bin/gcc  -mavx -nostdinc -isystem
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include -S repro.c
In file included from
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/xmmintrin.h:38:0,
                 from
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/x86intrin.h:34,
                 from repro.c:2:
/usr/lib/gcc/x86_64-redhat-linux/4.8.2/include/mm_malloc.h:27:20: fatal error:
stdlib.h: No such file or directory
compilation terminated.

This is because `mm_malloc.h' depends on malloc () / free () calls.

Maybe remove this dependence?
