Check compatibility options for using lua5.0

[Cody Tilkins]

I would like to add Lua-5.0 to the build category listing.

I am not sure which functions I will have to remove (or add :o) in order to include it.

[Cody Tilkins]

Compatibility is a maybe due to functions being added which I use in later versions. By stripping features, I can implement LuaConsole to support earlier Lua versions. The code may result in being messy or I can figure out a clean way to do it. Whatever the case I will look into it.

This is a capture of the errors and warnings that print out. It seems there are various function names that change. This isn't too surprising, as 5.0 and 5.1 aren't backwards compatible and shouldn't be expected to be. The same with previous versions and versions a set above that. However, it shouldn't break lua code at all. I think that is reserved for the first number as they follow this versioning: incompat.compat.patch where incompat breaks functionality between versions, compat alters functions but nothing should break, and patch are general purpose patches that don't alter much of anything.

Breakdown symbol -> suggestion : naming error, function may change, arguments may change

• error_test_meta
  • luaL_typename -> lua_typename : name
• load_parameters
  • lua_createtable -> lua_settable : name, function, arguments
  • lua_pushinteger -> lua_pushnumber : function
• load_globals
  • lua_getfield -> lua_getfenv : name, function, arguments
  • lua_setfield -> lua_setfenv : name, function, arguments
• luacon_loaddll
  • luaL_newstate -> lua_newtable : name, function, arguments
  • lua_gc -> lua_h : name, function, arguments
  • LUA_GCSTOP
  • luaL_openlibs -> luaL_openlib : name
  • LUA_GCRESTART
    note: each undeclared identifier is reported only once for each function it appears in
