BTW a great trick to unravel (evil) cpp macros is to deliberately insert a compilation error. gcc then shows the entire stack of macros involved. Much easier than cc -E or something.

Same trick with build systems and many other situations with "too many layers of indirections": deliberately injecting errors is often a great shortcut.

(none of that available at run-time of course)
