FYI, gdb is working just OK with the readline emulation found in
libedit, which has been written about a year and a half ago (just
around NetBSD 1.3 release cut) and not touched afterwards. It
doesn't seem gdb is using anything special or really needs some
exact readline version. So it should be fairly well just use system
libreadline :)

gdb doesn't touch readline internals so much as e.g. bash, so it
doesn't depend on any exact features to be present.

I'd prefer gnusrc/gnu/dist/gdb/readline or whatever directory gdb uses.
Note that no other program in NetBSD tree is using readline and should not
(bc and some-other-I-forgot program with readline support are using
libedit with the readline emulation).
BTW - readline "API" is just totally horrible IMHO.
