Comment (by m7.thon@…):

 Let me get this straight. To enable (partial) backward compatibility with
 say lua 5.2 two things are required:

 * lua 5.3 ''itself'' needs to be compiled with backward compatibility
 enabled by adding {{{-DLUA_COMPAT_5_2}}} to the {{{CFLAGS}}} (and this is
 done in the macports version of lua)
 * any port that uses deprecated lua 5.2 C-API calls needs to ''also''
 compile with {{{-DLUA_COMPAT_5_2}}} to get backwards compatibility (or it
 can be patched to use the current lua C-API)

 Is this correct?
