The include search path ends in:
  .
  /usr/lib/gcc/x86_64-redhat-linux/6.1.1/../../../../include/c++/6.1.1
 
/usr/lib/gcc/x86_64-redhat-linux/6.1.1/../../../../include/c++/6.1.1/x86_64-redhat-linux
 
/usr/lib/gcc/x86_64-redhat-linux/6.1.1/../../../../include/c++/6.1.1/backward
  /usr/lib/gcc/x86_64-redhat-linux/6.1.1/include
  /usr/local/include
  /usr/include

GCC finds 
/usr/lib/gcc/x86_64-redhat-linux/6.1.1/../../../../include/c++/6.1.1/cstdlib, 
and #include_next <stdlib.h> picks up the copy in /usr/include.

Does this answer your question?

Thanks,
Florian
