	hsearch family.
	* misc/hsearch.c, misc/tsearch.c: New files.
	* misc/Makefile (routines): Add efgcvt_r, hsearch_r, hsearch, tsearch.

	* posix/unistd.h (ttyname_r): Add prototype for new function.

	* stdlib/drand48_r.c, stdlib/erand48_r.c, stdlib/jrand48_r.c,
	stdlib/lrand48_r.c, stdlib/mrand48_r.c, stdlib/nrand48_r.c,
	stdlib/seed48_r.c, stdlib/srand48_r.c, stdlib/lcong48_r.c,

	and l64a() functions from SysV library.
	* stdlib/Makefile (routines): Add drand48_r, erand48_r, lrand48_r,
	nrand48_r, mrand48_r, jrand48_r, srand48_r, seed48_r, lcong48_r,
