It would be really convenient if the C preprocessor exposed the number of
variable arguments supplied to a variadic macro as an integer. I tried to come
up with ways of working around this missing feature, but I can't figure out how
to do it without evaluating the macro arguments twice or causing compiler
warnings.
I can supply a patch, if I am blessed with my proposed solution, to have
__VA_ARGC__ be an integer count of the number of __VA_ARGS__. If you have
suggestions for a better design, I'd like to hear them!
Thanks,
Michael.
