devel/gdb6* broken with new readline?

[Frank Mayhar]

I'm trying to do a full upgrade of everything for the first time in a
while.  After many gyrations, I've run into something that appears to
not be my fault :-):

cc -O2 -fno-strict-aliasing -pipe -DRL_NO_COMPAT       \
                -o gdb gdb.o libgdb.a \

Stop in /usr/ports/devel/gdb66.

It fails the same way with devel/gdb6.  I did a bit of searching and
apparently this is a known problem with the latest readline that was
fixed in gdb 6.8.
