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.
