"make clean" removes all of the files which are generated by the
"make" step. "make distclean" first performs "make clean" then also
removes any files which are generated by the "configure step".

If configure or any of the *.in files have changed, it is necessary to
run "make distclean" before compiling. Otherwise, "make clean" is
sufficient. It's safest to just use "make distclean" whenever the code
is updated.
