	* sysdeps/unix/sysv/linux/powerpc/Dist: Add kernel_*.h files.

1997-03-23 01:41  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/powerpc/strlen.s: Rewrote for more speed.

1997-03-19 06:11  Geoff Keating  <geoffk@ozemail.com.au>

	* sysdeps/unix/sysv/linux/powerpc/statbuf.h: Removed.
	* sysdeps/unix/sysv/linux/powerpc/kernel_stat.h: Added.

	* sysdeps/powerpc/dl-machine.h (ELF_PREFERRED_ADDRESS): Assume
	program base address is 0x01800000 if we can't otherwise tell what
	it is.
	(elf_machine_rela): Replace `assertion failed' with real error
	messages.

	* sysdeps/powerpc/dl-machine.h: More comments, more GNU indenting.
	Put in extra parentheses to make explicit the relative precedence
	of + and >>.

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

	* 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>.
