oleo 1.0's configure.in doesn't include the check for AC_ISC_POSIX.
This makes it not get the POSIX features in ISC 2.2.1.  Perhaps some of
the other variant checks should be included as well.

Also, io_term.c fails to compile on ISC 2.2.1 with gcc 2.3.1, because it
uses the identifiers TRUE, ERR, and FALSE, and doesn't define them.

Also, the clean targets seem confused:
  clean shouldn't remove parse.tab.c;
  distclean should depend on clean, and (perhaps) not remove core;
  realclean should depend on distclean, and remove parse.tab.c.

Also, Makefile.in should say
  exec_prefix = $(prefix)

instead of /usr/local, so that changes to $(prefix) will be reflected in
$(exec_prefix) by default.

There is no NEWS file.
