Compile a stub main which calls either main51 or main5x, link it against both static libraries to produce an executable.

Problem is, it is only at the final linking step that  externals are resolved. With the approach above, there will be conflicting externals (same names) from lua51.dll and lua5x.dll. The intermediate static library step does not change that (at least not without some other hackery).

It would really be greatl if Lua had built-in means to support multiple versions in a single executable.
