Fixed blatant stupidity in Core::ParseRatioC which checked the "sign" of in rather than valE.
Fixed minor stylistic mistake.
Use () instead of {} for initializers of reference members in order to please gcc.
Similarly, explicitly convert CounterRefs to pointers in some bool ? nullptr : CounterRef expressions.
Addressed some gcc warnings.
Addressed gcc -Wshadow warnings and added Bytecode::Info::put* functions.
