Subject: Fixed compiler improvements and added comprehensive test suite

- Fixed makefile preprocessor macro definitions (removed spaces in -D flags)
- Added null pointer check in compiler class declaration handling
- Added comprehensive test specifications for various language features:
  - attrib, backcall, cond, config, existential, export, goto
  - import, literals, macro, metatable, operators, return
  - string, switch, vararg, with
