Subject: Fix Lua 5.3 compatibility code.
X-Git-Tag: lxc-1.1.3~89
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=57a64031b6c727d9ba43841c126ab5429714db15;p=thirdparty%2Flxc.git

Fix Lua 5.3 compatibility code.

If Lua 5.3 is compiled with LUA_COMPAT_5_2 defined, the
luaL_checkunsigned compatibility macro is already defined
in lauxlib.h.
