Fixed problems on systems using newer GLIB and GCC (2.96) which no

longer allow the -Wp,-lang-c-c++-comments directive.  Also cleaned
up getloadavg support that had problems on Solaris and RedHat 7.1.
Removed unused variables in a number of functions as a result of
warnings when compiled with --enable-debug config option.
