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.

dms: include target configuration header
crc_csum.cpp uses UAE target types through the DMS headers. Include
sysconfig.h first so those target type definitions are available
before the archive declarations are parsed.

isofs: avoid undefined timezone sign extension
make_date() sign-extends the ISO9660 timezone byte when the high
bit is set. (-1 << 8) shifts a negative signed value, which is
undefined behavior in C++.
Use ~0xff to build the same extension mask without relying on
that undefined shift.

native2amiga: pass signal state as pipe pointer
write_comm_pipe_pvoid stores a pointer-sized value. Cast the
processed-state token through void * at the call site so the helper

softfloat: drop stale float_raise declaration
float_raise() is provided as a static inline helper by
softfloat-specialize.h. Remove the separate external prototype from
softfloat.h so the header does not advertise a non-existent external

softfloat: copy mod/rem quotient through uint64_t
floatx80_mod() and floatx80_rem() take a uint64_t quotient pointer,
while the FPU wrapper stores the quotient in uae_u64. Copy through a
temporary so the call does not depend on those typedefs being the same
type on every host.

softfloat: use lowercase macro header name
The source already includes the macro helper as softfloat-macros.h.
Rename the tracked file to match that spelling so case-sensitive file

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.
