New Revision: 234856
URL: http://svn.freebsd.org/changeset/base/234856

Log:
  GNU/kFreeBSD portability fix. This glue <stdlib.h> overrides header protection
  in the system-wide version of <stdlib.h> by wrapping the #include_next
  <stdlib.h> within the scope of its own header protection. On FreeBSD this has
  no effect, since both header protections are equivalent. However the GNU version
  of <stdlib.h> implements a special header protection mechanism which allows it
  to be included multiple times (in different modes).
  
  Simply by moving the #include_next off the header protection, we allow
  system-wide <stdlib.h> to implement its own protection policy, whichever that
  may be.
