? Strange. I would expect ok compile, but no readline functionality at
the end.

This is because the -L/home/frey/b/janku/lib/sun4/readline doesn't
appear on the linking command.

First check that you actually *have* readline/history.h...

Probably it isn't easy to persuade autoconf to do the right thing. A
better plan should be this:
Start with a clean source tree
(1)
make acclean # just so there are no config.cache or similar files
# floating around
(2)
./configure
(3)
edit src/include/Platform.h to contain
#define HAVE_LIBREADLINE 1
#define HAVE_READLINE_HISTORY_H 1
(4)
edit src/unix/Makefile to contain
system.o: system.c ../include/Defn.h
$(CC) $(CFLAGS) -I/home/frey/b/janku/lib/sun4/ -c system.c
(5)
edit src/main/Makefile to contain
LIBS=-ldl -ltermcap -lm -L/home/frey/b/janku/lib/sun4/readline -lreadline
#(not quite sure whether it must go last, and whether that might cause
trouble)

Wrong. It could be useful to many people, so I'm Cc-ing this back
to R-help.
