gmtime, localtime, mktime, strftime and asctime took and returned the
host std::tm. The guest's FreeBSD tm has tm_gmtoff and tm_zone after the
nine calendar fields, so on Windows, where std::tm is 36 bytes, a title
reading those fields read past the thread-local result, and gmtime_s left
them unwritten. Windows gmtime_s also accepts only 1969-12-31 12:00 to
3001-01-19 21:59 UTC, where the guest libc converts any time.
Convert through a GuestTm with the guest layout on both hosts. Compute
the UTC fields from the day count, so every time whose year fits an int
converts, and on Windows take the local offset and zone name from the
CRT. gmtime reports the zone as UTC like the guest libc. localtime and
mktime keep the CRT's range on Windows; recorded in TechnicalDebt.

On Windows, nanosleep and this_thread::sleep_for/sleep_until go
through winpthreads, which ends a wait on a 15.6 ms GetTickCount64
step. Blocking sceAudioOutOutput and sceAudioOut2ContextPush calls
returned in bursts about every 16 ms, a blocking sceAudio3dPortPush
ran at about 68 % of real time, and sceAudioInInput without a device
woke anywhere from 1 ms to 31 ms apart. They now sleep with
PreciseSleepUs or the new PreciseSleepUntil.

The guest's unsigned long is 64 bits. _Stoul was declared with the
host's unsigned long and returned std::strtoul, which are 32 bits on
Windows (LLP64): "4294967296" clamped to 4294967295 with ERANGE and
"-1" gave 0xffffffff, so a guest std::stoul threw out_of_range on values
the console accepts. It now returns std::uint64_t from std::strtoull,
as strtoul_nid_postfix and _Stoull already do; on Linux nothing changes.
The binary-prefix check stays in front of the host call.
Reported in #2424 by AchrafReyani; the same change was proposed in #2442
by SurajKhanna, whose two guest_math cases are taken here. Folded in at
MarcZX100's suggestion on #1459.

wcstol, wcstoll, wcstoul and wcstoull parse the ASCII prefix of the
guest's UTF-16 text with std::strtoll and std::strtoull, which glibc 2.38
and later bind to the C23 __isoc23_* functions: wcstol(u"0b101", &end, 0)
returned 5 with the end pointer after the whole string. They now check
StopAtBinaryPrefix_nid_no_patch first, like the narrow functions, and the
end pointer maps back through ParseAsciiPrefix as before.

C17 has no binary prefix: with base 0 or 2, strtol("0b101", &end, base)
reads the subject "0", returns 0 and leaves end at the 'b'. With glibc
2.38 or later, g++ (which defines _GNU_SOURCE) binds std::strtoll,
strtoull, strtoul, strtoimax and strtoumax to the C23 __isoc23_*
functions, which accept 0b/0B: the Linux exports returned 5 and
consumed the whole string. The Windows UCRT already follows C17, so the
same guest call gave different results on the two hosts.
strtol, strtoul, strtoll, strtoull, _Stoull, strtoimax, strtoumax and
_Stoul now return 0 with the end pointer after the '0' when, after
white space and an optional sign, the text starts with 0b or 0B and a
binary digit, in base 0 or 2. Everything else still goes to the host
function. The scanf family's %i has the same glibc behaviour; it is
recorded in TechnicalDebt.

FreeBSD vsyslog logs the complaint with LOG_ERR|LOG_CONS|LOG_PERROR|LOG_PID passed as the priority (0x23), not LOG_ERR.

ps5-opengl (PPSA99005) and ProsperoRadio (PPSA99001) import syslog
from libSceLibcInternal. Messages go to stderr with the priority, and
the format follows FreeBSD's vsyslog: %m expansion, masking of unknown
priority bits, LOG_USER as the default facility, errno preserved.

A title that replaces the allocator through its libc parameters also
supplies malloc_stats_fast in that table, and PPSA28997 calls it. It is
now forwarded to the title's function. Without a replacement allocator
that provides it, the call throws.
PICO-8 for PS5 (PPSA99808) stops at start-up on the unresolved import
a7ToDPsIQrc from libSceLibcInternal. The parser follows FreeBSD's inet_aton
(lib/libc/inet/inet_addr.c): one to four parts in decimal, octal or hex, the
last part filling the remaining bytes, input ending at a NUL or whitespace,
and a null address only validating.

PICO-8 for PS5 (PPSA99808) imports stpcpy from libSceLibcInternal, one
of the absent imports #1578 lists for it. POSIX defines it as strcpy
that returns a pointer to the terminating null of the copy.
RetroArch (PPSA99169) imports ldiv from libSceLibcInternal, one of the
absent imports #1578 lists for it. The guest long is 64-bit, so the
export takes std::int64_t and returns lldiv_t, which has the guest
ldiv_t layout; std::ldiv would truncate on Windows, where long is 32-bit.
The repo allows one implementation per export. Move libc's rename into
libc/src/Rename.cpp, compile that file into both libc and libkernel, and
drop the second copy from libkernel's Stdio.cpp. FilesystemError moves to a
header so the shared source can use it.
The test now checks that the symbol it resolves belongs to libkernel (module
handle on Windows, dladdr on Linux) so it fails when the export is removed.

Clang's PS4 and PS5 targets set the default new alignment and the suitable
alignment to 32 bytes, so PS5 code may store to a fresh malloc or operator
new result with 32-byte-aligned AVX instructions. The guest heap aligned
blocks to 16 bytes, and the arena's 32-byte classes put every small block
16 bytes past a 32-byte boundary after its header, so such a store faulted.
The minimum alignment is now 32 bytes; the padding still assumes only the
16-byte alignment the raw blocks guarantee.

Resolve ASCII case differences in guest paths and mount aliases while preferring exact names and rejecting ambiguous fallback matches. Preserve new filenames and host roots. Five filesystem tests pass; Skyrim now loads its INI and shader archives, initializes Vulkan and uploads intro textures instead of dereferencing null shader metadata. Written with AI assistance.
Preserve files across unmount, block new lookups until remount, and validate mount-dependent operations. Keep prior-run storage inaccessible after initialization.

Guest C built with -fexceptions binds __gcc_personality_v0 to
__gcc_personality_v0_nid_postfix, and the unwinder recognizes the frame
by that address. exception_c_cleanup links the host personality, so it
passed without the export.
The new test builds a call-site table by hand and drives the routine the
way the unwinder does: through the _nid_postfix symbol and through
CallPersonality. It covers the cleanup phase installing the landing pad,
the search phase continuing, ranges before and after the call site, a
call site with no landing pad, no LSDA, a signal frame, an unsupported
version, and an unknown personality. Without the export it fails to link.
On macOS the host keeps libc++abi: libc++ binds __cxa_throw two-level,
so moving only the personality into this runtime would leave the two
halves disagreeing on the exception header. The host personalities stay
libc++abi's and libunwind's, and libc.prx serves guest code:
- the guest's libstdc++ std::exception_ptr is modelled directly, since
libc++'s differs, and the Itanium type_info layouts that libc++abi
keeps private are declared for the runtime;
- guest frames are found through their PT_GNU_EH_FRAME, using a
dl_iterate_phdr emulation over the ELF program headers that relinked
images keep in __APS5DATA,__meta (written by relinker --macos, which
comes in a later pull request);
- host frames are found by scanning __TEXT,__eh_frame;
- sceKernelGetModuleInfoForUnwind uses the same emulation and falls back
to dladdr for host images.
The libc++ paths compile only with libc++/libc++abi and the rest only
on __APPLE__, so Linux and Windows builds are unchanged.
exception_c_cleanup throws from host code, which this runtime does not
serve on macOS, so it is not built there.
