cstdlib (at_quick_exit, quick_exit): Do not declare.

2013-02-11  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/c_std/cstdlib (at_quick_exit, quick_exit): Do not declare.
	* include/c_global/cstdlib (at_quick_exit, quick_exit): Declare only
	in C++11 mode and if available in the underlying C library.
	* testsuite/18_support/quick_exit/quick_exit.cc: Compile with
	-std=gnu++11; check _GLIBCXX_HAVE_AT_QUICK_EXIT and
	_GLIBCXX_HAVE_QUICK_EXIT.
