[$(have-initfini)=yes]: Test this rather than $(elf) for crtstuff. [start-installed-name-rule]: If this is defined, elide rule for $(objpfx)$(start-installed-name). * sysdeps/unix/sysv/sco3.2.4/Makefile [$(subdir)=csu] (start-installed-rule, start-installed-name-rule): New variables; specify crt1.o, created by our own rule. ($(objpfx)crt1.o): New rule. * configure.in: Require autoconf 2.4.2 or later. Change all AC_CACHE_VAL uses to use new AC_CACHE_CHECK macro instead; prettify some messages. [$elf!=yes] (libc_cv_have_initfini): New test for `.init' and `.fini' sections. * munch-tmpl.c [HAVE_INITFINI]: Call _init and atexit (_fini) in this case rather than #ifdef HAVE_ELF. * config.h.in (HAVE_INITFINI): New macro.
