	* sysdeps/unix/sysv/linux/ftime.c: New file.  Available system
 	call is only a stub.
	Reported by Matthias Urlichs.

	* Makeconfig [!default_cflags]: Change default value from `-g'
	to `-g -O'.

	* configure.in: Recognize i686.
	* sysdeps/i386/i686/Implies: Default on i586 optimized code.

Thu Aug  8 12:40:20 1996  Matthias Urlichs  <smurf@smurf.noris.de>

	* Makeconfig [$(build-omitfp) == yes]: Add to CFLAGS-.so
	value of CFLAGS-.o, not CFLAGS-o.

	* sysdeps/unix/sysv/linux/init-first.c (init): Add volatile
	pointer to ourself.  Otherwise `gcc -O3' optimized init away.

	sure that all tables in binary file are word-aligned.
