The tree carried two prebuilt Lua static libraries and a copy of the Lua public headers. lua51.lib is 5.1.2 and matched the headers; lua51.vc9.lib is 5.1.4 and was dead weight — it came second in Ja2_Libraries, so the linker resolved every Lua symbol out of lua51.lib and never pulled an object from it. Just as well, since it asks for /DEFAULTLIB:MSVCRT while we build /MT. ext/lua-5.1.5 is the upstream tarball unmodified, built as lua51 the way the other vendored libraries are, and its src directory replaces lua/ as the home of lua.h, luaconf.h, lauxlib.h and lualib.h. Those four headers were stock 5.1.2 retabbed, so 5.1.5 is bugfix-only against what the game compiled against; the bytecode format is unchanged across 5.1.x and every script under gamedir is plain source anyway. lua/lua.hpp had no includers and returns to etc/ where upstream keeps it. /SAFESEH:NO goes with it. Its two stated reasons were lua51.lib and the smackw32 import library, and both are now gone: every remaining prebuilt static library is SAFESEH-clean (libexpatMT.lib 5 of 5 members with @feat.00 = 0x1, RakNetLibStatic.lib 79 of 79), and lld-link emits a 3155-entry SEHandlerTable without it. The /MT comment blamed the wrong library. lua51.lib carried no linker directives at all; RakNetLibStatic.lib is what pins us to the static runtime, with /DEFAULTLIB:LIBCMT and /DEFAULTLIB:libcpmt. Verified by building all four applications in Debug and Release, and by linking the tarball's own lua.c against our lua51.lib with the build's clang-cl flags and running it under Wine: 5.1 stdlib, GC, coroutines and the x86 __asm fld/fistp lua_number2int fast path all behave. The game itself could not be launched here — this checkout's gamedir has loose Data directories but no SLF archives, so VFS aborts on Data\Ambient.slf long before any script runs.
