I'm for keeping the platform differences minimal. So in this case the structure produced by `make install` (though not very windowish) will work fine. I would rather update the default paths in `luaconf.h`.

The defaults currently are (added linebreaks for readability);
LUA_PATH
  !\\lua\\?.lua;
  !\\lua\\?\\init.lua;
  !\\?.lua;
  !\\?\\init.lua;
  .\\?.lua"

LUA_CPATH
  !\\?.dll;
  !\\loadall.dll;
  .\\?.dll

Change it to this;
LUA_PATH
  !\\lua\\?.lua;
  !\\lua\\?\\init.lua;
  !\\?.lua;
  !\\?\\init.lua;
  !\\..\\share\\lua\\5.2\\?.lua;       --> added
  !\\..\\share\\lua\\5.2\\?\\init.lua  --> added
  .\\?.lua"

LUA_CPATH
  !\\?.dll;
  !\\..\\lib\\lua\\5.2\\?.dll          --> added
  !\\loadall.dll;
  .\\?.dll

Then it includes the locations as produced by the makefile.

What does need to be updated in the toplevel makefile are these lines;

  # What to install.
  TO_BIN= lua luac

To:

  # What to install.
  ifeq ($(OS),Windows_NT)
  	TO_BIN= lua luac lua$(subst .,,$V).dll
  else
  	TO_BIN= lua luac
  endif

Because by default the .dll file is missing from an installation. Currently one must manually add `TO_BIN="lua.exe luac.exe lua52.dll"` to the `make install` command.
