In 3.2, you use lua_open. In 4.0, you can use lua_open too.
If you want the new, multiple-state API, then you call lua_newstate but you
have to #define LUA_REENTRANT before #include "lua.h".

We don't, but here is a script to creata .def from lua.h:

-- def.lua
-- make .DEF file from lua.h
-- usage: lua def.lua <lua.h >lua.def

T=read"*a"
write("LIBRARY LUA\nVERSION ")
gsub(T,"LUA_VERSION.-(%d+%.%d+)",write)
write("\nEXPORTS\n")
gsub(T,"(lua_%w+)%s+%(",function (f) write("   ",f,"\n") end)

Here is a script to add __stdcall if you need it.

-- stdcall.lua
-- add __stdcall where appropriate
-- usage: lua stdcall.lua <lua.h >s_lua.h
-- usage: lua stdcall.lua <lapi.c >s_lapi.c

T=read"*a"
T=gsub(T,"(lua_%w+%s+%()","__stdcall %1")
T=gsub(T,"(%*lua_CFunction)","__stdcall %1")

write(T)
