mame/3rdparty/sol2/sol/forward.hpp
Vas Crabb b5475eb38b Various updates, mostly around Lua: 
Compile Lua as C++.  When Lua is compiled as C, it uses setjmp/longjmp
for error handling, resulting in failure to unwind intermediate stack
frames.  Trying to ensure no objects with non-trivial destructors are in
scope when raising a Lua error is error-prone.  In particular,
converting an exception to a Lua error becomes convoluted, and raising a
Lua error from a constructor is effectively impossible.

Updated Lua to 5.4.4 - this includes a brand-new garbage collector
implementation with better performance.  The main thing removed is the
deprecated bitlib.

Updated sol2 to version 3.3.0 - this adds support for Lua 5.4 and fixes
a number of issues, including not correctly handling errors when Lua is
built as C++.

Updated LuaFileSystem to version 1.8.0 - this adds support for symbolic
links on Windows, as well as Lua 5.4 compatibility.

Updated LuaSQLite3 to version 0.9.5 - this fixes issues in
multi-threaded environments, as well as Lua 5.4 compatibility.

Fixed double-free after attempting to construct a debugger expression
from Lua with an invalid string, and exposed expression error to Lua in
a better way.

Added warning level print function to Lua.

Fixed saving cheats with shift operators in expressions, although this
code isn't actually used as there's no cheat editor.
