Yes, thanks. I've included a revised version of my patch below.

Well, gdbarch is never supposed to change the default behavior of
macros; this helps us convert pre-gdbarch targets incrementally.
Simply turning on gdbarch for one's target ideally wouldn't change its
behavior at all.

[Hurd needs 6. Take 8, since it does no real harm.]
Package: gdb
Severity: normal
Tags: patch, sid
Hello,
GDB will crash on the Hurd after issuing the 'show' and hitting enter
a few times:
../../gdb/ui-out.c:130: gdb-internal-error: push_level: Assertion +`uiout->level >= 0 && uiout->level < MAX_UI_OUT_LEVELS' failed.
the problem is that MAX_UI_OUT_LEVELS is not high enough for the extra
option we have on the Hurd, it should be rised to 6 then, which works
fine:

Hi,
gdb fails to build from source on m68k because some definitions have
been removed from tm-m68k.h. The patch below readds them.

Not yet submitted upstream. This requires some serious thinking about.
If the target stack worked in any logical way, this wouldn't be necessary...
ending up with roughly:
thread_stratum: thread-db (silent reference to lin-lwp)
core_stratum: corelow
exec_stratum: exec
dummy_stratum: dummy
just makes no sense.
This patch fixes debugging threaded applications which are statically linked
without breaking debugging threaded core files. It also fixes the PIDs in
generate-core-file'd corefiles. Mostly.
