--- Comment #4 from Max TenEyck Woodbury <mtewoodbury at gmail dot com> --- (In reply to jos...@codesourcery.com from comment #3) > We take the view that the preprocessor is deliberately meant to be limited > and overly complicated features in it would be contrary to the spirit of > C. Of course if they are introduced in the standard we need to implement > them, but otherwise this proposed feature seems inappropriate. That has not always stopped you all in the past, but that is really neither here nor there and you use the royal 'we' to boot... Speak for yourself. (ignore that; I'm in a sour mood and you just pushed one of my hot buttons.) Where option 1 may be a little complicated to implement, option 2, while less effective, is a real simple addition: define __VA_ARG_COUNT__ (or maybe __VA_ARGC__) with the same kind of restrictions that apply to __VA_ARGS__.
