r66179 | gregory.p.smith | 2008-09-02 22:57:48 -0700 (Tue, 02 Sep 2008)
Fix issue 3645: OpenBSD required -lcurses when linking with readline
to get the correct completion_matches function to avoid crashes on
x86_64 (amd64).

r66283 | gregory.p.smith | 2008-09-06 22:15:18 -0700 (Sat, 06 Sep 2008)
- Issue #1204: The configure script now tests for additional libraries
that may be required when linking against readline. This fixes issues
with x86_64 builds on some platforms (at least a few Linux flavors as
well as OpenBSD/amd64).
