This is a greatly pared down version of GDB-4.13 for FreeBSD 2.0. It
also has support for kernel debugging a la the dearly beloved kgdb.
Kernel debugging is enabled either using the -k flag or by linking gdb
to kgdb and invoking it as kgdb. Linking is left up to the discretion
of the user.
The kernel debugging needs testing, I didn't have any useful crash dumps
available. The new gdb produced the same output as the old kgdb with
what I had available for testing, though.
There's rudimentary support for attaching to a running process and
debugging (attach/detach commands in gdb). This works best if the
program being debugged was compiled with -g, of course.
Note that a plain vanilla gdb-4.13 without kernal debugging or
attach/detach support can be made by removing the
#define ATTACH_DETACH
#define KERNEL_DEBUG
lines from gdb/nm.h.
