(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) R=r OCL=15515 CL=15515
