This patch ought to have been enough:

But wouldn't you know it, gcc 2.96 prints a warning for *both* styles of
variadic macros! It's nice enough to warn that anonymous variadic macros
were introduced in C99 when you use that style, and nice enough to warn that
named variadic macros aren't standard C when you use that style. The
solution for this version of gcc looks like it's going to be a new entry in
the ignored warnings regex.

I'll commit the above patch if noone complains and if you don't beat me to it.
