+ getcwd: on Solaris, work better if ancestors are inaccessible
+ * lib/getcwd.c (__getcwd): If getcwd returns EINVAL for zero
+ buffer and size, try again with a large buffer. This works better
+ on Solaris, since its getcwd succeeds even if the path to the root
+ is inaccessible, and this is helpful in common cases such as .zfs
+ hidden directories. Problem reported by J Chapman Flack in
+ http://lists.gnu.org/archive/html/bug-tar/2010-06/msg00000.html
+ Use system getcwd if it's declared, not merely if it's partly
+ working; use the partly-working test only to avoid needless effort
+ if the system getcwd fails.
+ * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Omit

+ * lib/xmemcoll.c (xmemcoll0): Likewise.
+ * lib/memcoll.c (strcoll_loop): Tweak the way that the diff is

+ Include limits.h. Don't include string.h.
+ (HAVE_LDEXP_IN_LIBC, HAVE_RAW_DECL_STRTOD): Define to 0 if not defined.

+ check whether *s is a space.
+ (ldexp): Provide an unused dummy if not available.
+ (scale_radix_exp, parse_number, underlying_strtod): New functions.
+ (strtod): Use them. This implementation prefers to use the
+ underlying strtod if available, falling back on our own code
+ only to fix known bugs. This is more likely to produce an
+ accurate result. Also, it avoids the use of libm functions.
+ * m4/strtod.m4 (gl_FUNC_STRTOD): Don't invoke _AC_LIBOBJ_STRTOD;
+ no longer needed. Invoke AC_LIBOBJ([strtod]); don't know why this
+ was absent, but it caused a test failure with coreutils.
+ (gl_PREREQ_STRTOD): Check wither ldexp can be used without linking
+ with libm.

+ * lib/xmemcoll.c (collate_error, xmemcoll0): Likewise.
+ * lib/xmemcoll.h (xmemcoll0): Likewise.
+ * lib/memcoll.c (memcoll0): Correct the comment. This function
+ differs from memcoll in that the NUL byte is part of the argument.
+ Omit the abort-checks, as performance is a real issue here. Plus,
+ the checks were wrong anyway (an off-by-one error). Omit local
+ variable 'diff', as it's a bit clearer that way.
+ * m4/memcoll.m4 (gl_MEMCOLL): Omit AC_FUNC_STRCOLL, as it's
+ no longer needed.
+
