So this did not work:

C:\###\source>luarocks install luafilesystem
Installing https://luarocks.org/luafilesystem-1.7.0-2.src.rock

...

link -dll -def:lfs.def -out:lfs.dll C:/Program Files 
(x86)/PUC-Lua/5.3.4/x86/lua53.dll src/lfs.obj

...

C:\Program Files (x86)\PUC-Lua\5.3.4\x86\lua53.dll : fatal error 
LNK1107: invalid or corrupt file: cannot read at 0x448

I'm surprised nobody using LuaRocks have chimed in. So nobody uses 
Visual Studio for LuaRocks? One would think a linking step should 
work fine assuming forward compatibility, _if_ somebody had used 
it before...

Solution: Forget the C compilers. Distributions or modules should 
not need to use a C compiler. Which leads to the age-old issue of 
manpower, ha ha.

Or do it the ESP8266 way, distribute a Linux VM image with a 
cross-compiler targeting Windows and everything for a Lua distro 
loaded. Solves the "installing a suitable C compiler" problem.
