Research direction
Read section 6.10.4.1 of the C standard, then locate the TODO[#542] marker in the code. Trace the existing preprocessor handling for __VA_ARGS__ and ## and compare it with the standard's argument-substitution rules. Done means the applicable rules are implemented and their behavior is verified against the standard.
