+ longlong: tune, particularly for common case of c99
+
+ * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Don't bother compiling
+ or running anything if c99, or if unsigned long long int does not
+ work. In either case, we know the answer without further tests.
+ Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice. Instead, compile
+ it at most once, and use its results for both long long int and
+ unsigned long long int. This is more likely to be efficient in
+ the common case where the program wants to check for both long
+ long int and unsigned long long int.
+ (AC_TYPE_UNSIGNED_LONG_LONG_INT): Don't bother compiling if c99,
+ since the answer is already known.

+
+ getloadavg: set errno
+ * lib/getloadavg.c: Set errno when returning -1. If no other
+ error number looks appropriate, set it to ENOSYS if the getloadavg
+ looks like it can't possibly ever work, ENOTSUP otherwise.
+ Suggested by Bruno Haible in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-02/msg00187.html>.
+
+ getloadavg: trim unused parts and speed up 'configure'
+ * NEWS: Document this.
+ * lib/getloadavg.c: Ignore HAVE_GETLOADAVG; this file is now
+ always compiled if getloadavg is absent.
+ Move test code to ...
+ * tests/test-getloadavg.c: New file, containing previous
+ contents of test from lib/getloadavg.c. It also contains
+ suggestions by Bruno Haible in
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-02/msg00186.html>.
+ * modules/getloadavg-tests: New file.
+ * m4/getloadavg.m4 (gl_GETLOADAVG): Do not check for getloadavg twice.
+ Do tests in the same order as they're needed for getloadavg.c.
+ Omit setgid-related tests that generate symbols KMEM_GROUP,
+ NEET_SETGID, GETLOADAVG_PRIVILEGED; nobody seems to use those any more.
+ Do only the tests that are needed to see whether the system has
+ getloadavg, moving the other tests into ...
+ (gl_PREREQ_GETLOADAVG): ... here. Do not define obsolete symbol
+ NLIST_NAME_UNION; nobody should be using it. Do not define
+ symbols C_GETLOADAVG and HAVE_GETLOADAVG; they're no longer
+ relevant, as the user of this module shouldn't care how getloadavg
+ is implemented.
+
+ getloadavg: omit unused var
+ * lib/getloadavg.c (getloadavg): Omit unused local variable.
