cd32_fmv: include libmpeg2 headers as C
The external libmpeg2 headers declare a C API. Wrap them in
extern "C" when they are included from C++ so the CD32 FMV decoder

archive: support official LZMA SDK 16.04 APIs
The bundled 7z reader used older SDK field names directly. Keep the

UAE_7Z_SDK_1604 path for the public 16.04 headers.
Select the matching XZ finish constant by SDK family so the shared

chd: make LZMA and inline helpers portable
Use the public LZMA property writer to build decoder properties
instead of the MAME-only allocator helper. This keeps the CHD LZMA
path compatible with the stock SDK interface.
Make ATTR_FORCE_INLINE produce inline definitions on GCC and Clang so
header-defined helpers can be included safely by multiple translation
units. Define PTR64 from CPU_64_BIT when the build has not already
provided it.

The generic Unix exception path works with ucontext_t directly. Use that

gfxboard: rewind Picasso IV flash before autoconfig
Picasso IV autoconfig is read from the flash image, but the
initializer can run more than once while the expansion list is
scanned and sorted. loadp4rom() leaves the flash zfile positioned
later in the image, so a later dry scan read all-0xff data and the
board looked like it had no autoconfig block.
Seek back to the beginning before reading the Picasso IV
autoconfig bytes so repeated scans see the same board data.

jit/x86-64: fix FPU FLDCW codegen crashes on 64-bit hosts
The x86-64 JIT could crash when compiling FPU rounding-mode changes
(FLDCW with an indexed operand) via two defects in codegen_x86.cpp:
1. x86_64_rex() dereferenced its 'b' (REX.B) pointer unconditionally and
ignored 'r'/'x'. raw_fldcw_m_indexed() passes its index register in the
'x' (REX.X) slot with b == NULL, so the function read through a NULL
pointer; an index register in r8-r15 would also have been mis-encoded.
x86_64_rex() now null-guards each pointer and emits REX.R/X/B (and W).
2. raw_fldcw_m_indexed() loaded the 64-bit base of the x87 control-word
table into RAX. RAX is allocatable (not in always_used[]) and may hold a
live m68k value mid-block, and a LOWFUNC cannot declare a register
clobber, so the allocator's view of RAX was silently corrupted; a later
access through that register (e.g. MOVEM.L ...,-(An)) then dereferenced
the table pointer as an m68k address and faulted. The base is now
materialized in a push/pop-preserved scratch register chosen to differ
from the index register.
Only x86-64 is affected; the 32-bit path uses a direct FLDCW [reg] encoding
and ARM64 uses different codegen.
Enable the ARM64 JIT build path, keep natmem above 4GB, reserve the full direct-memory window, commit read-only natmem gaps, and install a Windows ARM64 vectored exception handler for JIT access faults.
Add a GitHub Actions Windows ARM64 binary job that installs the ARM64 MSVC tools and builds winuae_msvc.vcxproj directly without ARM64-building host generator projects.
Validated with ARM64 Release and FullRelease MSBuild builds, plus VMware Windows ARM64 runtime logs showing the handler catching ramsey_low probes instead of crashing.
