- psx_cyc.h / psx_cycles.c: _BitScanForward/_BitScanReverse shims for __builtin_ctz/__builtin_clz under _MSC_VER - full_function_emitter.cpp / main_psx.cpp: emit a portable .CRT$XCU init-pointer instead of GCC-only __attribute__((constructor)) in generated dispatch/game code - main.cpp: declare cross-language globals extern "C" so MSVC links them against their C definitions (no-op for GCC/Clang) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
