+ 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.

+ * 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.
