	* scripts/config.sub: Recognize alpha{pca5[67],ev[67]}.

	* sysdeps/generic/elf/backtracesyms.c (__backtrace_symbols):
	Format pointer differences as longs.

	* sysdeps/alpha/fpu/s_floor.c, sysdeps/alpha/fpu/s_floorf.c:
	Copy commentary from bits/mathinclude.h.  Kill unused defines.

	* sysdeps/alpha/atomicity.h: New file.
