* sysdeps/generic/sysd-stdio.c (__stdio_reopen): Return failure
 	when __stdio_open fails with a code other than ENFILE or EMFILE.

	* csu/initfini.c (SECTION): New macro, different definitions for
 	#ifdef HAVE_ELF and not.
	(_init, _fini): Use that macro.
	* config.make.in (have-initfini): New variable, set by configure.
	* conf/portability.h (NEED_INETADDR, NEED_INETATON): New macros.
