Tue Nov 7 12:29:46 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>

	* elf/linux-compat.c: New file.
	* elf/Makefile (distribute): Add linux-compat.c.
	(generated): Add librtld.so.
	[$(config-os)=linux*] (extra-objs): Add linux-compat.so.
	[$(config-os)=linux*] (extra-objs): Add ld-linux.so.1.
	(librtld.so): New target.
	(ld.so, ld-linux.so.1): Make from librtld.so.

	* elf/rtld.c (dl_main): Instead of weak call to _dl_compat_init,
	call our own DT_INIT if we have one (and then clear it).
	(__dgettext): New weak function.

	* intl/localealias.c (read_alias_file): Avoid sprintf; use memcpy
	by hand instead.

	* sysdeps/generic/_strerror.c (_strerror_internal): Use _itoa
	instead of snprintf.

	* sysdeps/mach/_strerror.c (_strerror_internal): Don't write
	BUF[BUFLEN].

	* elf/rtld.c (rtld_map): New static variable.
	(_dl_start): Use a differently named local BOOTSTRAP_MAP for the
	bootstrapping.  Then copy data into `rtld_map'.
	(dl_main): Finish filling in rtld_map and link it into the chain,
	instead of allocating a new structure.
	(dl_main): Call _dl_compat_init if it is defined (use weak ref).

	* elf/dlsym.c: Fix last change: move REF out of `doit'.
