	* acinclude.m4 (GLIBCXX_ENABLE_CHEADERS): Add c_global.
	* configure.host (c_model): Set default to c_global.
	* configure: Regenerate.
	* include/Makefile.am (c_compatibility_headers_extra): Make
	conditional on GLIBCXX_C_HEADERS_COMPATIBILITY.
	(c_base_headers_extra): Make conditional on GLIBCXX_C_HEADERS_EXTRA.
	(c_compatibility_headers): Make conditional on c/c_std/c_global.
	* include/Makefile.in: Regenerate.
	* docs/html/configopts.html: Add c_global information to
	--enable-cheaders. Eventually, "c_std" should mean "C" includes
	that are in namespace std, with optional C++ "C" compatibility
	includes to inject into global scope. And "c_global" should mean
	"C" includes that are in the global namespace, with C++ includes
	injecting into namespace std and no C++ "C" compatibility
	includes.
