[Rd] How to compile R with command completion?

[Peng Yu]

I didn't change anything except --prefix when I compile readline. Here
is my $LD_LIBRARY_PATH which has the directory where libreadline.so is
in. I also copied 'conftest.c' to a temp dir and compiled it with
-lreadline and -lcurses (this is manual testing, not using configure).
The problem of "conftest.c:(.text+0x8): undefined reference to
`rl_completion_matches'" is resolved.

Why '-lreadline' and '-lcurses' are not in the command called by
'configure'? Is this a bug in configure? How should I fix it?
