+	doc: document Solaris printf bug with large float precisions
+	* doc/posix-functions/dprintf.texi (dprintf):
+	* doc/posix-functions/fprintf.texi (fprintf):
+	* doc/posix-functions/printf.texi (printf):
+	* doc/posix-functions/snprintf.texi (snprintf):
+	* doc/posix-functions/sprintf.texi (sprintf):
+	* doc/posix-functions/vdprintf.texi (vdprintf):
+	* doc/posix-functions/vfprintf.texi (vfprintf):
+	* doc/posix-functions/vprintf.texi (vprintf):
+	* doc/posix-functions/vsnprintf.texi (vsnprintf):
+	* doc/posix-functions/vsprintf.texi (vsprintf):
+	Mention that these functions mishandle large floating point
+	precisions on Solaris 10.  The same bug is also present in Solaris
+	8, and I assume earlier.  This causes "cd gnulib-tests; make
+	check" to fail on Solaris 8 (and I assume, later) when building
+	the latest coreutils, in test-vasprintf-posix's call to
+	my_asprintf (&result, "%.4000f %d", 1.0, 99).  I have not checked
+	the wide flavors (e.g., wprintf) so this patch just updates the
+	documentation for the narrow ones.
+
+	test-posixtm.c: add two tests
+	* tests/test-posixtm.c: Add two tests, to highlight the
+	bug in Solaris 10 (and earlier) localtime.  Gnulib doesn't work
+	around this bug; this is merely to document it.

+
+	getlogin_r: Work around portability problem on OSF/1.
+	* m4/getlogin_r.m4 (gl_FUNC_GETLOGIN_R): Detect the OSF/1 problem.
+	* lib/unistd.in.h (getlogin_r): Replace if REPLACE_GETLOGIN_R is set.
+	* lib/getlogin_r.c (getlogin_r): When getlogin_r exists, invoke it and
+	test for a truncated result.
+	* m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Initialize REPLACE_GETLOGIN_R.
+	* modules/unistd (Makefile.am): Substitute REPLACE_GETLOGIN_R.
+	* modules/getlogin_r (Depends-on): Add memchr.
+	* doc/posix-functions/getlogin_r.texi: Mention the OSF/1 problem.

+	ptsname: Avoid test failure on OSF/1 5.1.
+	* modules/ptsname-tests (Depends-on): Add 'same-inode'.
+	* tests/test-ptsname.c: Include <sys/stat.h>, same-inode.h.
+	(same_slave): New function.
+	(main): Use it to compare ptsname's result with the expected file name.

+	* doc/posix-functions/ttyname_r.texi: Mention the OSF/1 bug.
+	* m4/ttyname_r.m4 (gl_FUNC_TTYNAME_R): Detect the OSF/1 bug. Say "no"
+	instead of "guessing no" when the OSF/1 bug or the Solaris bug is
+	present.
+	* lib/ttyname_r.c (ttyname_r): Update comments.
