The Windows -include of HostStandardStreams.hpp pulled in stdio.h before
libstdc++ could set __USE_MINGW_ANSI_STDIO, so long double formatting
bound to UCRT. Define the MinGW flag and include cstdio for C++.
Host logging opens its own FILE on the saved descriptor. The guest FILE stays on the replaced descriptor, so guest printf, puts and fprintf still reach the pipe.
A path whose directory part is a regular file, such as file/child, failed
with ENOENT in open, stat, lstat, access and unlink on Windows, where
FreeBSD 11.4 lookup fails it with ENOTDIR (vfs_cache_lookup, sys/kern/vfs_cache.c).
mkdir and rmdir already did. A not-found error of these calls now asks whether the
nearest existing ancestor is not a directory and reports ENOTDIR then.

fdopendir listed the directory from its first entry whatever position the
descriptor had, and left FD_CLOEXEC unchanged. FreeBSD 11.4 fdopendir sets
FD_CLOEXEC on the descriptor and preserves the initial seek position (lib/libc/gen/opendir.c).
The Windows directory handle now skips the entries the descriptor already
consumed, the Linux handle duplicates the descriptor, and the test requires both.

rename and sceKernelRename resolved "dir/." to "dir" and renamed the directory. FreeBSD 11.4's lookup fails a last component of "." for DELETE and RENAME with EINVAL, for the source and the destination alike. Check the guest string before it is resolved: a last component of "." (also under trailing slashes) fails with EINVAL when its parent exists, ENOENT when it does not and ENOTDIR when it is not a directory.

MinGW libstdc++ up to GCC 16 does not treat a reparse point as a link in
std::filesystem::remove_all, so a host tree that holds a symlink is walked
through the link and never returns. Add RemoveTree, which removes the tree
itself on Windows, and use it where save data, app content and the shader
disk cache removed host trees. The libstdc++ fix is in GCC 17 (88856ad855ae).
An ANYPS5_ENABLE_ASAN build moves the guest arena up by 0x100000000000,
past AddressSanitizer's shadow gap, but the AGC driver memory that holds
the FS table (#6160) is still mapped at the fixed 0xfe0000000. That
address is in the shadow gap, so the mapping fails with EEXIST and no
test that initializes the driver runs under ASan.
The offset is now GuestArena::GuestAddressOffset in GuestArena.hpp, and
the driver memory and the FS table move by it like the arena. Builds
without ASan keep 0xfe0000000. agc_driver_compute_fs_table_calls skips
in an ASan build: its shader builds the PS5's fixed table address from
literals, as titles' shaders do, and that address can't be mapped there.

Copy the guest TZ under the guest environment lock so a concurrent setenv
cannot free it while it is read, and hold one lock across the zone switch
and the conversion so the fields of two zones are never mixed. Document the
host rejection, Windows zone name and stale tm_zone limits.
macOS's strtoll and strtoull set errno to EINVAL when the subject has
no digits, as in "", "words" or " +". The guest's integer conversions
pass that to the title, while guest_atoi, guest_wide_conversion and
guest_math expect errno unchanged, as glibc leaves it. So atoi("")
returned 0 with errno 22 on macOS, and all three tests failed there.
A ParseInteger helper in SonyCrt.hpp calls the host's conversion and,
on macOS, restores the caller's errno when nothing was converted and
the base is valid. An overflow still sets ERANGE, and an invalid base
still sets EINVAL. strtol, strtoul, strtoll, strtoull, atoi, atol,
atoll, _Stoull and the wcsto* integer conversions in Strings.cpp use
it. On other hosts the helper calls the conversion unchanged.
A shared mapping is a view of a file section created on the descriptor's
handle, read-write when the descriptor is, otherwise read-only. A private
mapping is a copy of the file read at mmap, as POSIX allows. Anonymous
shm_open objects and JIT shared memory descriptors are temporary files on
Windows, so mmap now maps them too (it failed with EOPNOTSUPP before).
mprotect of a mapped view above the view's protection fails with EACCES
before any bookkeeping changes. The cases Windows cannot represent are
listed in the libkernel debt.
Dusklight (PPSA99305) uses SQLite in WAL mode, which maps its -shm file.
On Windows main f0634088b every start logged "Failed to start
transaction: disk I/O error" for its Dawn and pipeline caches (3 of 3
runs); with this change the caches initialise and their WAL files fill
(4 of 4 runs). The title reaches its menu either way.
A shared mapping may end inside the 16 KiB page that holds the end of
the file, as POSIX mmap allows: the view ends with the file's last 4 KiB
host page, which Windows zero-fills past the end, the rest of the guest
page is private zero pages, and the file never grows. A mapping that
reaches a whole page past the end still fails with EOPNOTSUPP.
PS5LM Plus (PPSA99581) loads its model with llama.cpp, which maps the
whole GGUF file shared and read-only. With a 491,400,032-byte model,
Windows main 5de7a46e0 and this change without the last page logged
"llama_model_load: error loading model: mmap failed: Operation not
supported" (3 of 3 runs); now the model loads and the completion of
"The capital of France is" starts with " Paris" (3 of 3 runs).

fopen resolved the random device paths to a host file that does not
exist and failed with ENOENT, while open and sceKernelOpen already serve
them from host entropy. A read-only fopen of either path now returns a
stream whose fread fills the buffer with host entropy. setvbuf, feof,
ferror, clearerr, the stream locks and fclose work on it, fflush returns
0 as on a FreeBSD stream that is not writing, other stream functions
throw, and opening the paths for writing throws as in libkernel.
ProsperoTV (PPSA99003) reads its phone pairing code this way and showed
"Code expired or unavailable".

The console's libSceLibcInternal.sprx (measured on firmware 12.70 in
#7549) prints %p as bare lowercase hex without a 0x prefix, prints 0 for
a null pointer, ignores #, + and the space flag, counts only the digits
towards the width, pads with spaces on the left (on the right for - and
with zeros for 0 when there is no precision), treats the precision as
the minimum number of digits, prints nothing for a null pointer under
%.0p, and accepts the l length. FormatPointer instead followed FreeBSD
and printed 0x..., which is what a title does not see on hardware.
FormatPointer now prints the digits alone, the narrow Windows formatter
accepts %lp, and Linux routes %p and %lp to the guest formatter instead
of glibc, which prints the FreeBSD form and (nil) for a null pointer.
The wide family still refuses %lp, because the console's swprintf was
not measured with it; it returns -1 as it does for any other conversion
the formatter rejects. The debt note records the pointer cases the
console was not measured with and what the Linux routing means for a
format that mixes %p with a refused conversion.
fopen and freopen in an append mode gave the C runtime a descriptor with
_O_APPEND, which seeks to the end of the file and then writes. Streams on
separate descriptors overwrote each other's data. FreeBSD opens these
streams with O_APPEND, so every flush lands at the end of the file.
Open append streams with FILE_APPEND_DATA but without FILE_WRITE_DATA,
so Windows writes each flush at the end of the file. ftruncate and
flock reopen the file to get the access such a handle lacks.
Ship of Harkinian (PPSA99320) logs its heap use with malloc_stats_fast
every 10 s and stopped on the first call, since only an application
allocator could answer it. The default heap now keeps its system and
in-use byte counts with their peaks and fills the same managed-size
block as sceLibcMspaceMallocStatsFast, whose layout moves to a shared
header.

sysctl {CTL_KERN, KERN_PROC, KERN_PROC_VMMAP, pid} for the calling process
returns packed FreeBSD 11 kinfo_vmentry records, one per used range of the
guest arena, with the protection sceKernelVirtualQuery reports. Other pids
return ESRCH, a write EPERM, a short buffer ENOMEM. GuestArena gains a
query for the used range at or after an address.
