Done as follows:
2009-06-17 Bruno Haible <br...@clisp.org>
Define missing ESTALE on Interix 3.5.
* lib/errno.in.h (ESTALE): Assign a value if missing.
* lib/strerror.c (rpl_strerror): Handle missing ESTALE and ECANCELED.
* m4/errno_h.m4 (gl_HEADER_ERRNO_H): Also test whether ESTALE is
missing.
* doc/posix-headers/errno.texi: Mention the Interix bug.
