2011-02-16 Paul Eggert <eggert@cs.ucla.edu>
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.
2011-02-15 Paul Eggert <eggert@cs.ucla.edu>
Merge from gnulib.
