  (typo in ptr decl lead to an unresolved forward declaration)
- fixed parser bugs
- fixed Makefile
- now successfully parses most code

Issues:
- composite literals (cannot be identified easily from syntax alone)
- new(T, ...) (cannot be identified easily from syntax alone since
  new is not a keyword and thus could be a different function then
  the allocation function at which point "new((x + y))" is legal,
  but the inner "(x" looks like the beginning of a function type)

- code scavenged from Go-in-Go front-end (will merge back)
- using "symbol-table" free parsing to build AST
- no printing yet

	binary <- is send
	unary <- is recv
	-< is gone
	case a := <-ch: works in select
	case a = <-ch: works in select
support for new cases is not yet in the compiler but all non-select
code works

second CL will update affected go source
