Comment (by Prasad):
As I understand the mapping from signal number to string kept in the file
{{{
src/bin/bash/signames_haiku.h
}}}
The comment in the file suggest that the file is auto-generated using a
tool mksignames.
Running the tool shows the following output
{{{
prasad@pjoshi:~/sources/Haiku/haiku$
./generated/objects/linux/x86_64/release/bin/bash/mksignames

/* A translation list so we can be polite to our users. */

This seems to be exact list reported on a Linux system, I mean, the signal
name and position matches with Linux machine.
AFAIK, this auto-generated list cannot be used, since Haiku uses few
propitiatory signals like 'SIGKILLTHR' for example.
So the question I have is, How was the signames_haiku.h generated
initially? was it auto-generated?
If it was not auto-generated, would it be okay if I manually edit the file
and add SIGBUS at 30'th location?
