On FreeBSD 4.x GDB 6 needs the newer version of Readline provided by devel/readline and a newer GCC such as 3.4. Also kvm-fbsd.c conditionally redefined the function fbsd_kern_frame_saved_pc, but the didn't headers didn't hide the previous definition.
Responsible Changed From-To: freebsd-ports-bugs->obrien Over to maintainer
State Changed From-To: open->closed Acutally gdb6 never supported being run on FreeBSD 4.x as the port was to be a vehicle to upgrade the gdb in the 5.x base /usr/src. Anyway, I've committed the patch as it didn't break the build on 5.x. Note, that I didn't commit the sparc64 or amd64 parts since there aren't any 4.x systems of those platforms.
