+       Import getloadavg module from gnulib.
+       * .bzrignore: Add lib/stdlib.h.
+       * Makefile.in (GNULIB_MODULES): Add getloadavg.
+       * admin/notes/copyright: Remove src/getloadavg.c as a special case.
+       * configure.in (LIBS_SYSTEM): Omit -lkstat on sol2*; gnulib does this.
+       (AC_CONFIG_LIBOBJ_DIR, AC_FUNC_GETLOADAVG, GETLOADAVG_FILES):
+       Remove; gnulib does this now.
+       * lib/getloadavg.c: Rename from src/getloadavg.c, and sync
+       from gnulib.  This adds support for several other systems, such
+       as Tru64 4.0D, QNX, AIX perfstat, etc.  It also fixes a potential
+       buffer overrun on Linux hosts under very high load, and on hosts
+       that maintain a channel to the load average file it makes sure
+       the file descriptor is close-on-exec (on hosts that support this)
+       and is not stdin, stdout, or stderr.
+       * lib/stdlib.in.h, m4/getloadavg.m4, m4/stdlib_h.m4: New files,
+       from gnulib.
+       * aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
+       * src/config.in: Regenerate.

 +      * lib/getloadavg.c, lib/stdlib.in.h, m4/getloadavg.m4: New
 +      versions from gnulib.
