There was a problem hiding this comment.
Can this #if be refactored into a header (perhaps ar.h?) so we can avoid copying it into ar_entry.c?
From http://lua-users.org/wiki/CompatibilityWithLuaFive: luaL_reg (Lua 5.0) changed its name to luaL_Reg since Lua 5.1. Apply the recommended fix to support lua 5.1 and prior versions.
Use lua_getuservalue()/lua_setuservalue() instead of the removed lua_getfenv()/lua_setfenv().
Replace the deprecated functions with their libarchive 3.0 replacements as listed at: https://github.com/libarchive/libarchive/wiki/ManPageLibarchiveChanges3
"wrote" was checked against -1 but was never actually set.
When running the tests, libarchive says: InvalidFFlag: 'archive' is not a known fflag So remove that one flag from our tests.

Note that I had to disable the "__gc" functions for the code to work and the tests to pass on Lua 5.3. I don't think that the existing code should regress on 5.1 or older, but I'm still investigating the problems with newer Lua versions. |

It at least compiles and loads for me. |

Lua 5.2 and 5.3 support, as well as porting to libarchive 3.0.
Untested.
