* elf/elf.h (AT_GID): Fix typo: Read -> Real. * misc/efgvt_r.c: New file. Reentrant version of [efg]cvt functions. * misc/efgcvt.c: Rewrite to use reentrant functions. * misc/hsearch_r.c: New file. Reentrant version of functions from 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, stdlib/drand48-iter.c: New files implementing reentrant versions of functions from drand48 family. * stdlib/seed48.c, stdlib/drand48.c, stdlib/erand48.c, stdlib/jrand48.c, stdlib/lrand48.c, stdlib/mrand48.c, stdlib/nrand48.c, stdlib/srand48.c, stdlib/lcong48.c: Rewrite to use reentrant versions. * stdlib/a64l.c, stdlib/l64a.c: New files. Implement a64l() 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, drand48-iter, a64l, l64a. * stdlib/stdlib.h: Declare them. * stdlib/random_r.c: New file.

Close AT_ENTRY case with `break'. * sysdeps/generic/strstr.c: New and much faster implementation by Stephen R. van den Berg. * sysdeps/generic/_strerror.c: _strerror_internal now takes three argument and has and explicit buffer length. * sysdeps/mach/_strerror.c: Change for new interface with three arguments. * stdio/perror.c, stdio/vfprintf.c: Callers changed. * sysdeps/mach/hurd/ttyname_r.c: New file.
