This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

/* The underlying idea is that when a Windows program is terminated by
|
|
a fatal exception, its exit code is the value of that exception, as
|
|
defined by the various EXCEPTION_* symbols in the Windows API
|
|
headers. We thus emulate WTERMSIG etc. by translating the fatal
|
|
exception codes to more-or-less equivalent Posix signals.
|
|
|
|
The translation below is not perfect, because a program could
|
|
legitimately exit normally with a status whose value happens to
|
|
have the high bits set, but that's extremely rare, to say the
|
|
least, and it is deemed such a negligibly small probability of
|
|
false positives is justified by the utility of reporting the
|
|
terminating signal in the "normal" cases. */
