+ 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
+ comment that was already obsolete and is now even more obsolete.
+ * modules/getcwd (Depends-on): Depend on strdup, since __getcwd
+ now might call strdup.
