Can you provide references? I'd like to understand why it was rejected - it seems to be the "official" approach to the problem. > does solve this specific issue fine, there were other more general > problems; IIRC (and I might not) it completely changes the way macro > expansion happens, which results in it being pretty useless. Hence, "-x > assembler-with-cpp" was chosen over e.g. "-ansi". Again, do you have any reference? "completely changes the way macro expansion happens" sounds terribly dangerous, so it would be better to know about that exactly...
