The last architecture I'm aware of where it would make a difference was the old HP-3000 16-bit stack architecture (obsolete since 1986), where the arguments were laid out in the wrong order. (And it's way too old and obsolete to have a gcc port, anyway :-/). Normally, args on such architectures are laid out such that the first argument is at a known (negative) offset from the stack frame base, and the others have increasing (negative) offsets. The HP-3000 was *ss-backwards, in that the first argument had the largest negative offset, with each succeeding argument having a smaller negative offset, so you had to go through incredible calisthenics to support varargs.. Max: keep looking for those nitpicky errors, though - the next one may be significant.. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
