	of + and >>.

	* sysdeps/powerpc/bsd-setjmp.S: Add `__setjmp' symbol so the tests
	pass.
	* sysdeps/powerpc/clone.S: Rewrite.  Probably still doesn't work.

1997-03-31 02:28  Ulrich Drepper  <drepper@cygnus.com>

	* misc/tst-tsearch.c: Don't write to stderr, write to stdout
	instead.

	* inet/inet_ntoa.c (inet_ntoa): Complete rewrite.  Now uses
	thread-specific memory in multi-threaded programs.

	* sysdeps/stub/s_exp2.c: New file.  Stub version for exp2 function.
	* sysdeps/stub/s_exp2f.c: New file.
	* sysdeps/stub/s_exp2l.c: New file.
	Reported by a sun <asun@zoology.washington.edu>.

	* sysdeps/unix/sysv/linux/netatalk/atalk.h: Rename to...
	* sysdeps/unix/sysv/linux/netatalk/at.h: ...this.
