>Description:
When trying to remotely debug the kernel, I found out that
the ddd from pkgsrc (ddd-3.3.8nb1) doesn't work. There seems
to be a problem with ddd<->gdb interface, as plain gdb seems
to work fine.

When running DDD, I get the following on the terminal:

gdb: cannot set terminal foreground process group: Inappropriate ioctl for 
device

This happens almost immediately when starting ddd,
and it doesn't matter if I'm running it as the root
or as a regular user. I can't even issue the "cont"
command to the target, it fails already in the beginning.

>How-To-Repeat:
1. Install NetBSD-current.

2. Set up kernel debugging environment following the instructions
   in NetBSD documentation.

3. Install ddd from pkgsrc.

4. Try to debug with ddd.
>Fix:
I tried this, but it doesn't change anything:

$ cvs diff gnu/usr.bin/gdb53/Makefile.inc
