--include-deps

[Owen Taylor <otaylor redhat com>]

A bunch of the patches you've submitted include changes to
autogen.sh like:

+case $CC in
+*xlc | *xlc\ * | *lcc | *lcc\ *) am_opt=--include-deps;;
+esac
+if test -n "$CC" && echo $CC | grep -v gcc >/dev/null 2>&1; then
+        $CC -v 2>&1 | grep gcc || am_opt=--include-deps
+fi
+

The two halves of this seem be rather unrelated and tacked
together, and this will, among other things result in parts
of gcc -v being printed to standard out in some cases. 
Is the intent supposed to be something like:

if test -n "$CC" ; then
  my_cc=$CC
else
  my_cc=cc
  IFS="${IFS= 	}"; save_ifs="$IFS"; IFS="${IFS}:"
  for dir in $PATH; do
    if test -x $dir/gcc ; then
      my_cc=gcc
    fi
  done
  IFS="$save_ifs"
fi

case $my_cc in
  *xlc | *xlc\ * | *lcc | *lcc\ *) 
    am_opt=--include-deps
    ;;
  *gcc | *gcc\ *)
    ;;
  *)
    $CC -v 2>&1 | grep gcc > /dev/null || am_opt=--include-deps
    ;;
esac
