Thanks for your comments.

in the makefile.mgw

# Where to install the PostScript prologue files, relatively to the executable
# wgnuplot.exe
GNUPLOT_PS_DIR = share/PostScript

# Similarly for javascript files for the canvas terminal:
GNUPLOT_JS_DIR = share/js

# Similarly for scripts used by the lua terminal
GNUPLOT_LUA_DIR = share/lua

Then 'share/lua' relative to gnuplot executables. 
So that /gp45-winbin/gnuplot/bin/share/lua is the place to put the file 'gnuplot-tikz.lua'.

This is the similar way to the PostScript prologue files.

However as you pointed out

gnuplot> set term tikz
Terminal type set to 'tikz'
error: cannot open D:\usr\Tatsu\mingwhome\gnuplotcvs\gp45-winbin\gnuplot\share/lua\gnuplot-tikz.lua:
No such file or directory. Lua context closed.  

This might be a bug of newly imported code for windows into lua.trm.

For the second remark I am not a lua user.
I cannot answer your remark.

I ask you to subscribe to gnu...@li... and discuss there.

Anyway I appreciate your kind suggestions.

Regards

Tatsuro
