* 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.
