Capability SIDs (S-1-15-3-...) have been introduced with
Windows 10 1909. They don't resolve with LookupAccountSid.
We don't need them and they don't map gracefully into out
POSIX account namespace. Also, add code to make sure to
filter them out *iff* they become resolvable at one point.
While at it, slightly reorder code for non-resolving SIDs
by authority values.

If a removable (USB) device is disconnected after opening its raw
device, R/W attempts fail with ERROR_NO_SUCH_DEVICE(433). If the
raw device of a partition is used, ERROR_MEDIA_CHANGED(1110) is
returned instead. Both are mapped to ENODEV(19) because <errno.h>
does not offer a value which better matches ERROR_MEDIA_CHANGED.

Windows only allows to set the primary group to a group already
present in the TOKEN_GROUP list. Cygwin OTOH fakes success at
setgid() time, to allow a subsequent call to setuid() to do
the actual account switching. To have a sane behaviour in the
command line tool, check group membership and disallow to switch
to groups other than those already present in the user token.

The %p format specifier is handled immediately. It requires
that tm_hour is already set. This falls flat in case the am/pm
marker preceeds the time specification. Locales with am/pm
marker preceeding time spec by default exist (e. g. ko_KR).
Also, the code expects that tm_hour might be set to an invalid
value because the %p specifier is used in conjunction with %H.
But this usage is invalid in itself and now catched as error
condition after commit 343a2a558153 ("Cygwin: strptime: make
sure to fail on invalid input digits").
Change the %H/%I/%p handling according to GLibC, i. e.
- fix tm_hour for pm only if the time value has been specified
as 12 hour time %I, and
- perform the fixup only after the entire input has been scanned.
This decouples the fixup from the %p position relativ to %I.

conv_num returns NULL if the input is invalid, e. g., the
numbers are out of range. However, the code fails to test
this in a lot of places.
Rather than adding checks all over the place, rename conv_num
to __conv_num and create a wrapper macro conv_num to perform
the task of error checking.

...in a non-Cygwin child process. Backported from MSYS2.
Downstream commit message follows.
In https://github.com/msys2/msys2-runtime/pull/18, we discussed a change
that would allow default Windows error handling of spawned processes to
kick in (such as registered JIT debuggers). We even agreed that it would
make sense to hide this functionality behind a flag, `winjitdebug`.
However, when this got upstreamed as 21ec498d7f (cygwin: use
CREATE_DEFAULT_ERROR_MODE in spawn, 2020-12-09), that flag was deemed
unnecessary.
But it would appear that it _is_ necessary: As reported in
https://github.com/msys2/MSYS2-packages/pull/2414#issuecomment-810841296
this new behavior is pretty disruptive e.g. in CI scenarios.
So let's introduce that `winjitdebug` flag (settable via the environment
variable `MSYS`) at long last.

If specified, use __builtin_dynamic_object_size() instead of
__builtin_object_size() if supported (GCC 12.0 or later).
This enables buffer overflow checks if the buffer size is non-const
but known during runtime.
Use new macro __ssp_bos_known() instead of the (bos(p) != (size_t)-1)
checks. The latter is no longer a compile time constant in all cases.

it to newlib. Redefine how it indicates fork state (not

A process which is exiting due to a core dumping signal doesn't
propagate the correct exist status after dumping core, because 'dumper'
itself forcibly terminates the process.
Use 'dumper -n' to avoid killing the dumped process, so we continue to
the end of signal_exit(), to exit with the 128+signal exit status.

This patch is required to fix how the newlib headers are installed
when using a sysroot install directory.
The cross compiler expects headers to be in
.../host/usr/arm-none-eabi/sysroot/usr/include/newlib.h
by default newlib installed the headers into
.../host/usr/arm-none-eabi/sysroot/usr/arm-none-eabi/include/newlib.h
${exec_prefix} provides the .../host/usr/arm-none-eabi/sysroot path
${target_noncanonical} provides an extra arm-none-eabi/ that must be removed.

Strip a few more instructions from crt0-minrt.S:
- Remove "halt" and rely on the infinite loop after main()'s return.
- Remove main()'s argc and argv argument initialization. Host loader
does not set them, and typical firmware does not use them, either.
- Remove the __dso_handle symbol.
This should be safe because the default crt0.S is fully standards
compliant. Whereas crt0-minrt.S has been documented from the beginning
to intentionally miss features in order to reduce firmware size, while
still enabling typical PRU firmware to operate.

While at it, fork crt0-minrt.S into a separate source file instead of
relying on a predefined macro to generate two different object files.
This improves clarity, simplifies the build rules, and would allow
further optimization in crt0-minrt.S to be implemented more cleanly.

When creating a split manual with one-node-per-page, the main index.html
ends up getting clobbered by the page for the index() function because
it uses "@node index" which, for html, also creates an index.html page.
To remedy this, add "Function " to every function node so now we output
"Function-index.html" and avoid clobbering. It also namespaces every
other function and helps make sure we don't clobber anything else.
Otherwise, there isn't really much rendering difference as @node text
is mostly internal. Node title text comes from @section instead.
The generated function documentation makes sure to include entries for
every function in the function index via @findex, but then the manuals
forget to actually print the index.
Wrapping the dir info with @ifnottex means it's included in all other
outputs like html which makes no sense. Switch to @direntry which is
specific for this content and is automatically written to the output
that makes sense, and omitted from the rest.
